Terms of use

Last updated 3 November 2026

1. Who we are

Sketchfest (sketchfest.ai) is run by BNER Limited, a private company limited by shares incorporated in Hong Kong (company number 80898063), with its registered office at Unit 1603, 16/F, The L. Plaza, 367-375 Queen's Road Central, Sheung Wan, Hong Kong. You can reach us at [email protected]. In these terms, "we" means BNER Limited and "you" means the person or business using Sketchfest. These terms are the agreement between you and us for using Sketchfest. You buy paid plans from us, and Stripe takes the payment (section 7). All our details are on the company details page.

2. What Sketchfest does

Sketchfest turns hand sketches, and screenshots of CAD drawings and 3D models, into images using artificial intelligence (AI). The images are made by AI models from other companies, at present OpenAI, with Microsoft as a backup (see the privacy policy). AI results vary: the same drawing can give different images, and an image may not follow your drawing exactly or may show things that are not in it. The images are visual studies, not technical or construction drawings. Render times we show are typical, not promised.

3. Your account

You sign in with a code or a link we email you, or with Google where we offer it. There are no passwords, so keep access to your email account safe: anyone who can read it can sign in. An account is for one person; please do not share it. You must be at least 16 to use Sketchfest, and if you are under 18 you need the permission of a parent or guardian. To buy a plan you must be an adult where you live. Please use an email address you read, because we send sign-in codes and links, downloads and notices about your plan there, and keep your details up to date.

4. The free render

Everyone can make one free test render. You give us your email address and we send you a 6-digit code and a link: typing the code, or opening the link, confirms the address, opens your free account and starts the render. Both work for 24 hours. There is one free render per person, per email address (an address with a +tag, or a Gmail address with dots, counts as the same address), per account and per device, with a daily limit for each network, and a quick check by Cloudflare Turnstile tells people from bots. If you never use the code or the link, your drawing is removed after 2 days, and its locked safety copy 90 days after that (privacy policy, section 8). We may refuse free renders obtained through several accounts, throwaway email addresses or automated tools.

5. Credits

Sketchfest works with credits. Every action shows how many credits it uses before you start: a test render uses 1 credit, a final image in 2K 5 credits, and a 4K print image 10 credits. Final images in 2K and 4K come with a plan. Costs can change over time, but the cost shown when you start is the one that applies.

Credits are not money. They have no cash value, cannot be transferred or sold, and can only be used on Sketchfest. Credits come with your plan every month and are for that month only: unused credits do not roll over and expire when the next month's credits are due. If a renewal payment is late, your leftover credits stay usable for up to a day while it goes through. Yearly plans get their credits month by month, on the same rule. Extra credits from an upgrade expire with the month they were added to. When your plan ends, its unused credits expire with it.

If a render fails, its credits go back to your account automatically. Every drawing, the words you add and every render go through an automatic safety check, and our AI providers have their own filters too (section 10). If one of them stops a render, it does not run or is not delivered, and its credits come back too.

6. Plans

Sketchfest works by subscription. There are three plans, Basic, Plus and Pro, each with a set number of credits every month, billed monthly or yearly. A plan renews automatically at the end of each period until you cancel. You can cancel at any time on the Billing page. The plan then runs to the end of the period you paid for, you keep its credits until then, and it does not renew. Before a yearly plan renews, you get a reminder by email.

You can move to a bigger plan at any time: you pay the difference for the rest of the current period, at the price shown before you confirm, and get the extra credits straight away. A move to a smaller plan, or between monthly and yearly billing, starts at your next renewal. If we change the price of your plan, we tell you at least 30 days before it applies to you, and you can cancel before then.

7. Prices and payment

Who sells your plan: BNER Limited sells the plans and provides the Sketchfest service. Stripe, our payment provider, takes the payment on its secure checkout page and emails you the receipt.

Prices: in euros. The price shown is the full price you pay. If you buy for a business, tick that you are purchasing as a business at checkout and add your company name and VAT number; you can also add them, with your address, on the Billing page. They appear on your invoices from then on.

Payment: by card, Apple Pay, Google Pay or Link, on Stripe's checkout page. We never see or store your full card details. Your receipts and invoices also appear on the Billing page. If a plan payment fails, it is tried again and we let you know by email; that month's credits arrive once the payment goes through. If it keeps failing, the plan ends.

Help with a payment: write to us at [email protected]. If a payment was taken by mistake or without your permission, tell us and we put it right.

8. Cancelling within 14 days, and refunds

If you are a consumer in the European Union or the United Kingdom, you can withdraw from a purchase within 14 days of buying it, without giving a reason: use Withdraw from contract on the Billing page, or write to us at [email protected], and we confirm by email. Before you pay, you tick a box to ask for your plan to start straight away and to accept these terms and the privacy policy, and your credits are ready as soon as you pay. So if you cancel within the 14 days, you pay for what you have already used, as consumer law allows. What you used is counted in credits, at your plan's price per credit: the price you paid divided by the credits your plan gives for that period. For example, Basic monthly is €9 for 60 credits, so €0.15 a credit; Basic yearly is €90 for 720 credits, so €0.125 a credit. We refund the rest to the payment method you used within 14 days, and your plan and its credits end when you withdraw. We keep a record of your tick (the time, your network address and your email address) to show that you asked. Consumers elsewhere may have a similar right under their local law.

Otherwise, payments are not refundable, including for unused credits or the unused part of a period, except where the law requires it or section 12 applies. We look at other refund requests case by case. If a payment is refunded, the unused credits it bought are removed from your account in proportion. If a render fails, its credits come back to your account by themselves. Your legal rights if Sketchfest does not work as described are not affected (section 13).

9. Your drawings and the images you make

Your drawings stay yours. You allow us to store your drawings, your words and the images you make, and to process them, including sending them to our AI providers, only to run Sketchfest for you and keep it safe. This ends when you delete them, except for a locked safety copy that we keep for 90 days, and longer only while a report or safety flag about it is open or the law requires it (privacy policy, section 8). We look at them only as the privacy policy describes, and neither we nor our AI providers use them to train AI models.

We claim no rights in the images you make: as far as there are rights in them, they are yours. You can use them for any lawful purpose, including client work, portfolios, competitions and commercial work. AI can make similar images for other people, so we cannot promise that an image is unique or that it can be protected by copyright. Some competitions and clients have rules about AI images, so check them before you submit.

Images made with Sketchfest carry metadata that marks them as made with AI, as the EU AI Act requires. Please keep it. If you publish an image that people could mistake for a real photograph of a real place or event, say that it was made with AI where the law requires it.

You confirm that you have the right to upload what you upload, and that it does not break the law or anyone else's rights.

10. What you must not upload or make

Sketchfest is for visuals of architecture, interiors and landscape. Do not upload, write or make any of the following, in a drawing, in your words or in a render:

• Sexual content or nudity of any kind, and anything that sexualises children. We report child sexual abuse material to the authorities.
• Violence: gore, cruelty to people or animals, weapons used to harm, and anything that promotes terrorism, violent extremism or self-harm.
• Hate, harassment or threats against anyone, including because of race, ethnicity, nationality, religion, disability, sex, gender identity, sexual orientation or age.
• Real people who can be recognised, without their permission.
• Images made to deceive, such as fake evidence or fake documents, or a render passed off as a photograph of a real building to mislead buyers, authorities or a jury.
• Other people's work or data: drawings, designs, photos, logos or trademarks you have no right to use, or personal details of other people that you do not need, such as faces, names or number plates.
• Anything else that is illegal where you are or in Hong Kong, or that breaks the usage rules of our AI providers (Microsoft and OpenAI).

Do not try to get around the safety checks, credit limits, free-render limits or payments; share your account; or scrape, copy, resell, reverse engineer, overload or probe the service, or use bots or scripts on it without our permission.

How we keep to these rules: every drawing, the words you add and every render go through an automatic safety check before anyone sees the result, and our AI providers have their own filters. What they stop is not rendered or not delivered, and its credits come back. A person on our team then reviews what was stopped, as the privacy policy describes. We may remove content that breaks these rules and suspend or close accounts. For a serious or repeated breach we may close the account at once, without a refund for the current period, except where the law requires one. We report illegal content, above all child sexual abuse material and credible threats, to the police or the responsible authority, and keep it as long as they or the law require. Where we can, we tell you first, give our reasons and let you respond.

11. Reporting content

If you think content on Sketchfest is illegal or breaks these terms, email [email protected] with where it is, why you think so, and your name and email address. We look at every report promptly and tell you what we decided. If we remove your content or limit your account, we tell you why, unless section 14 allows us not to, and how to challenge the decision; a person reviews every challenge.

12. Availability and changes

We work to keep Sketchfest running, but we cannot promise it will always be available or free of errors. We may change, add or remove features, and change the AI models we use. If we stop a feature you pay for, or close Sketchfest, we tell you at least 30 days in advance and refund the part of your plan you have not used.

13. Liability

Nothing in these terms limits the rights you have as a consumer by law, including your rights if Sketchfest does not work as described (in the EU, the rights for digital services under Directive (EU) 2019/770; in the UK, the Consumer Rights Act 2015), or liability that cannot be limited by law, such as for death, personal injury, fraud or gross negligence. If you are a consumer, we are responsible for loss you suffer that was foreseeable and caused by our breach of these terms.

If you use Sketchfest for a business, our total liability to you in any 12 months is limited to what you paid in those 12 months, and we are not liable for indirect losses such as lost profit, lost business or lost data.

Sketchfest images are visual studies. Check them before you rely on them for design, planning, construction or legal purposes.

14. Ending your account, and when we can end it

You can delete your account at any time on the Account page. This deletes your projects and images and ends your plan at once. Credits you have left are lost, and the rest of the current period is not refunded, without affecting your rights under consumer law. We keep our payment records for as long as accounting and tax law require.

Suspending an account: we may suspend your account at once, without notice, while we look into a suspected breach of these terms, fraud, a payment dispute or chargeback, a security risk, or a request from an authority. A suspended account cannot sign in or render, and its plan stops renewing.

Closing an account for a reason: we may close your account at once, without notice, if you break these terms seriously or repeatedly (section 10), act fraudulently or abusively, try to harm Sketchfest or other people, or if the law or an authority requires it. You then get no refund for the current period, except where the law requires one.

Closing an account for any other reason: we may also close your account, or stop offering Sketchfest to you, for any other reason. We then tell you by email at least 30 days before, and refund the part of your plan you have not used.

Reasons: we usually tell you why. We may give no reason, or a short one, where the law does not allow more, where it would harm an investigation or someone's safety, where it would help someone get around our safety systems, or when we close an account with notice (above). If you think we made a mistake, reply to our email and a person will look at it again.

New accounts: we may refuse to open an account or sell a plan to anyone, and if we closed your account for a reason, you may not open a new one without our permission.

15. Changes to these terms

If we change these terms in a way that matters, we email you at least 30 days before the change applies. If you do not agree, you can cancel your plan and delete your account before then.

16. Law and disputes

These terms are governed by the law of the Hong Kong Special Administrative Region. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you can bring a claim in the courts there. If you use Sketchfest for a business, the courts of Hong Kong decide any dispute. If something goes wrong, please write to [email protected] first: we reply within 5 working days.

17. Sanctioned countries and regions

We do not offer or sell Sketchfest to, from or within Cuba, Iran, North Korea, Syria, or the Crimea, Donetsk and Luhansk regions of Ukraine. You may not open an account, buy a plan or use Sketchfest if you are in one of these places or live there, if you act for a person or organisation there, or if you are named on a sanctions list of the United Nations, the European Union, the United Kingdom or the United States. If an account breaks this, we may suspend or close it at once (section 14).

Privacy policy

Last updated 14 October 2026

1. Who is responsible

BNER Limited, Unit 1603, 16/F, The L. Plaza, 367-375 Queen's Road Central, Sheung Wan, Hong Kong, runs Sketchfest and is the controller of your personal data (the "data user" under Hong Kong's Personal Data (Privacy) Ordinance). For anything in this policy, write to our Privacy Officer, BNER Limited, Unit 1603, 16/F, The L. Plaza, 367-375 Queen's Road Central, Sheung Wan, Hong Kong, or at [email protected].

Wherever you live, including in the EU and the UK, you can write to us directly about your data, and we handle every request ourselves.

2. What we collect

• Account: your name, your email address, how you sign in, when you joined, and your choice about news and offers, with the date and the words you agreed to.
• Your work: the drawings you upload, the images you make, project names, any words you add, and your settings.
• Plans and payments: your plan and its dates, what you bought and when, the amounts, whether a payment went through or was refunded, your receipts and invoices, and the billing name, country, address, company and VAT number if you give them. Stripe handles your card; we only see its brand, the last four digits and the expiry date.
• Credits and activity: the credits you get and use, the renders you make and when, and which AI model made each image.
• Emails: a log of the emails we send you, and the messages you send us.
• Security: your network (IP) address, a random device ID kept in a cookie, browser details, the sign-in codes and links you ask for, and the result of Cloudflare's bot check.
• Safety checks: the result of the automatic check on each drawing, your words and each render, and, if something is stopped, why, when and from which network address.
• Visits, from the moment you open the site, unless you turn analytics and advertising off under Cookie settings: the pages you visit and when, how you arrived (for example from one of our ads), your device and browser, your approximate location from your network address, and steps such as signing up, starting a checkout or buying a plan, through Google Analytics and the Meta Pixel; for those steps our server also tells Meta, with your email address hashed (see Meta below).
• Your request to start a plan straight away: when you ticked the box before paying, your network address, your email address and your browser.

You need to give us an email address to have an account, because we sign you in and send your downloads with it. If you do not, we cannot open an account for you. Everything else is up to you. Please do not upload drawings with other people's personal data that is not needed.

3. Why we use it, and on what legal basis

News and offers: only if you tick the box, we use your name and email address to send you tips, news and offers about Sketchfest's own services. We never use them for this without your consent, and we never give them to others for their marketing. You can stop at any time with the unsubscribe link in every such email, or on your Account page.

Your right to object: where we rely on legitimate interest, you can object at any time, for reasons relating to your situation. We then stop, unless we have compelling reasons that override your interests, or need the data for legal claims.

We do not make decisions about you based only on automated processing that have legal or similarly significant effects on you.

4. How AI handles your drawings

To make an image, we send your drawing, your settings and any words you add to one of our AI providers, which processes them for us and sends back the image:

• OpenAI (GPT Image): every new render, from the free test render to final images in 2K and 4K.
• Microsoft (MAI-Image models in Microsoft Foundry): a test render, only when OpenAI is down and this backup is switched on.

They work under data processing terms with us. They do not use your drawings or images to train their models, and may keep them for up to 30 days only to detect abuse. We store the images they send back with your project. Make 2K and Make 4K enlarge a render you already made on our own server, without an AI provider.

The automatic safety check: before an engine sees your drawing, and before you see a render, both go, with any words you add, through OpenAI's moderation service, which looks for sexual content, violence, self-harm, hate, harassment and illegal activity. It does not use them for training. If it, or an engine's own filter, stops a render, the render does not run or is not delivered, your credits come back, and we keep a locked copy so that a person on our team can review it (terms, section 10). These checks only decide whether a render can go ahead; any decision about your account is made by a person.

Who can see them: only you. Our team cannot browse your drawings or renders. We open them only when you ask us for help with them, when they are reported or stopped by a safety check, or when the law requires it. Each time, we record who looked, when and why, and you can ask us for that record. If they are illegal, we may give them to the police or the responsible authority.

5. Who we share data with

Providers who process data for us, under contracts that oblige them to protect it and use it only on our instructions:

Companies that use your data as controllers in their own right:

• Stripe: processes your payments under its own privacy policy (stripe.com/privacy). It uses your payment and billing details to take the payment and, where the law requires it, to prevent fraud, and tells us what we need to run your plan. If you pay with Link, Link's privacy policy applies to your Link account (link.com/privacy).
• Google: if you sign in with Google, where we offer it.
• Meta (Meta Platforms Ireland Limited in the EU, EEA, UK and Switzerland; Meta Platforms, Inc. elsewhere): from the moment you open the site, unless you turn it off under Cookie settings, the Meta Pixel sends Meta what you do on our site, with its cookie and your network address. Our server also tells Meta, through Meta's Conversions API, when you start your free render, open an account, start a checkout or buy a plan: with your email address and account number in a scrambled form (hashed with SHA-256, which Meta matches against its own accounts), your network address, your browser and Meta's cookies, and for a purchase the price and your country. This also stops when you turn analytics and advertising off under Cookie settings. For collecting and sending this data, Meta and we are joint controllers, under Meta's Controller Addendum (Meta handles requests about it). Meta then uses it as a controller in its own right under its privacy policy (facebook.com/privacy/policy): to measure our ads, show them to you and to people like you, and to improve its ads. If you have a Facebook or Instagram account, Meta can link this data to it; you control your ad settings there.

We also share data, only as far as needed, with our professional advisers (such as accountants and lawyers) under a duty of confidentiality, with authorities when the law requires it, and with a buyer if Sketchfest is ever sold, in which case we tell you first. We never sell your data, and there are no ads on Sketchfest itself.

6. Where your data goes

Your account, drawings and images are stored on our server in Frankfurt, Germany. We are a Hong Kong company, and our team may reach that data from outside the EU. Some providers process data in other countries, mainly the United States (among them Google and Meta, for the visits they measure). Where data protection law asks for safeguards, we rely on an adequacy decision, such as the EU-US Data Privacy Framework and its UK extension for certified providers, or on the European Commission's standard contractual clauses, with the UK addendum for UK data. Wherever your data is processed, it gets the protection this policy describes.

7. How we keep it safe

Everything travels encrypted (HTTPS). Your drawings and images are only sent to your own signed-in browser, and links to them do not work for anyone else. Our team signs in with a password and an authenticator code, and every look at your files is logged. Card details stay with Stripe. If a breach puts your data at risk, we tell you and the authorities as the law requires.

8. How long we keep it

• Account, projects and images: until you delete them or your account.
• Locked safety copies: when you delete a drawing or an image, or your account, a locked copy, with the email address it belonged to, is kept for 90 days and then deleted. Only a reason, a fresh code and a log entry open it.
• What a safety check stopped, or what is reported: until a person has reviewed it, then 90 days. If it is illegal, as long as the law or the authorities require.
• A free render you ask for but never confirm: the drawing 2 days, then the locked safety copy for 90 days.
• Backups of our server: overwritten within 30 days.
• Credits and activity: as long as your account exists.
• Payment records, and your request to start a plan straight away: 7 years, as Hong Kong accounting and tax law requires. When you delete your account, they are no longer linked to it. Stripe keeps its own payment records.
• Consent for news and offers: while you are subscribed, then as long as we need to show you agreed.
• Emails we sent, and messages you sent us: 90 days in our email log. Replies stay in our mailbox as long as needed to help you.
• Sign-in codes and links: 30 days. Sign-in sessions: 90 days, or until you log out.
• Security records: network addresses of free renders 30 days, server logs 14 days, limits on repeated tries 2 days. The device ID of a free render stays for the life of its cookie (400 days), so each device gets one.
• The fact that an email address had its free render: 2 years after its account is deleted, so it cannot be used for another.
• Your data download: 7 days.
• Our team's access record: up to 6 years, the time limit for legal claims in Hong Kong.
• Visits in Google Analytics: 14 months, then deleted. Meta keeps Meta Pixel data under its own policy. The cookies themselves last as the cookies page says.

9. Your rights

You can ask to see, correct, delete or take a copy of your data, to restrict or object to how we use it (section 3), and you can withdraw consent at any time. Analytics and advertising: turn them off under Cookie settings, at the bottom of our pages. You can do most of this yourself on the Account page: download my data, delete my account, and email choices. For anything else, write to our Privacy Officer at [email protected] or BNER Limited, Unit 1603, 16/F, The L. Plaza, 367-375 Queen's Road Central, Sheung Wan, Hong Kong. We reply within one month and do not charge for it; we may ask you to confirm who you are. When you ask us to delete your data, we delete it, except the locked safety copies for their 90 days and what the law requires us to keep. Stripe keeps its own payment records, which you can ask Stripe about (stripe.com/privacy).

If you are unhappy with how we handle your data, please tell us first. You can also complain to a data protection authority: in the EU, the one where you live or work (in Spain, for example, the AEPD at aepd.es); in the UK, the Information Commissioner's Office (ico.org.uk); in Hong Kong, the Privacy Commissioner for Personal Data (pcpd.org.hk).

10. Cookies and local storage

We use what Sketchfest needs to work and stay safe and, unless you turn them off under Cookie settings, Google Analytics and the Meta Pixel to measure visits and our ads (section 3). The cookies page lists each one.

11. Children

Sketchfest is not for children under 16, and we do not knowingly collect their data. If you think a child has given us data, write to us and we delete it.

12. Changes

If we change this policy in a way that matters, we email you before it applies. The date at the top shows the latest version.

Cookies and local storage

Last updated 14 October 2026

Sketchfest uses the cookies and browser storage it needs to work and stay safe. From the moment you open the site, it also uses cookies from Google Analytics and the Meta Pixel, to measure visits and our ads. You can turn those off at any time.

When you pay, you are on Stripe's checkout page, where Stripe sets its own cookies for payment security and fraud prevention (Stripe's cookie policy).

How to control them

Analytics and advertising cookies: turn them off or on again under Cookie settings, also at the bottom of our pages. Turning them off deletes their cookies on our site. You can also use Google's opt-out (tools.google.com/dlpage/gaoptout) and your ad settings at Meta.

Your browser settings let you block or delete any cookies and stored data. If you block the sign-in cookie, you cannot stay signed in; if you clear the device cookie, it does not give you another free render.

Fonts

Our fonts load from our own server, so loading the page does not send your details to a font service.
