OneCanvas

Terms of Use

Effective and last updated October 21, 2026

These Terms are an agreement between you and OneCanvas (“we”) about your use of the OneCanvas app. By downloading, signing in to or using OneCanvas, you agree to these Terms and to the Privacy Policy. If you do not agree, please do not use the app.

1. Your account

2. Your content

You keep all rights to the photos, titles and text you create (“Content”). You allow us to store, process and display your Content as needed to run OneCanvas features: storing it on our servers, exhibiting it in rooms to everyone who can open them, placing it in a room’s hidden painting and creating posters when you share. This permission is non-exclusive and free of charge, and it ends when you delete the Content or your account, except for copies you have already shared with others.

You confirm that you have the rights to your Content and, where the law requires it, the consent of anyone who can be recognised in your photos.

3. Rules of use

When using OneCanvas, you must not:

We have no tolerance for objectionable content or abusive users. You can report a photo that breaks these rules with the Report photo button in the app or by email at the address in section 12, and block other users so you no longer see their photos. We review reports, may remove Content that breaks these rules, and may suspend or end the access of accounts that do.

4. Rooms and share codes

Each personal room has one of three visibility settings: Private (only you can see it), Anyone with the code (anyone with the room’s code or link can open it) and Public (visible to all users). Think before you share a code or link. You can change the code at any time; the old code and links then stop working.

Public and Anyone with the code rooms may let guests hang photos, one per guest; the owner can turn this on or off at any time. A room’s owner can take down any photo in their room, change its visibility or delete it. By hanging a photo in someone else’s room, you agree that its owner may do these things with your photo. A guest’s photo remains the guest’s Content and is still subject to section 3.

5. OneCanvas Plus

6. Intellectual property

The OneCanvas app, including its interface, 3D rooms, graphics, code and trademarks, belongs to us or our licensors, except for works in the public domain. You may not copy, modify, distribute or commercially exploit them without our written permission.

7. App licence

The app downloaded from the App Store is licensed to you under Apple’s standard Licensed Application End User License Agreement (EULA). These Terms add to that agreement.

8. Third-party services

OneCanvas uses Apple and Google services for sign-in, payments, notifications and analytics, and Supabase to store accounts, rooms and the photos you hang. Your use of Apple’s and Google’s services is also subject to their terms.

9. Disclaimers and limitation of liability

OneCanvas is provided “as is”. We work to keep the app running smoothly but do not guarantee that it will always be uninterrupted or free of errors.

The photos in your Collection are stored on our servers with your account, so they stay when you change devices or reinstall the app, but they are gone once you delete them or your account. Photos you hang in rooms are stored on our servers, but they are gone once you replace them, the room’s owner takes them down or deletes the room, or you delete your account; deleting your account also deletes your rooms from the server. So keep copies of photos that matter to you.

To the extent permitted by law, we are not liable for indirect damages arising from your use of the app. Nothing here limits the rights consumer protection law gives you.

10. Changes and termination

We may update the app, change or discontinue features, and revise these Terms. For significant changes, we will notify you in the app before they take effect. If you keep using OneCanvas afterwards, you accept the revised Terms.

11. Governing law

These Terms are governed by the laws of Vietnam. Disputes will first be settled through negotiation; failing that, they will go to the competent court in Vietnam. This does not take away any rights you have under the consumer protection laws of the country where you live.
