Terms

Terms of service.

Plain English. Updated 24 June 2026. Questions go to hello@getmostra.com.

1. The short version

Mostra is a platform that lets artists publish and sell their work, and lets collectors discover and acquire it. You are responsible for what you upload, sell, and say on the platform.

2. Accounts

You need an account to follow artists, save works, message, or sell. You must be at least 16. One person, one account. Keep your credentials safe.

3. Artists and artwork

You may only list original work you own and have the right to sell. You set your own prices. You own your collector relationships. Mostra never takes a commission on sales.

4. Subscriptions

Monthly and annual plans are non-refundable, including for unused time. You can cancel any time from your account and keep access until the end of the current paid period, after which the subscription ends with no further charges.

5. Collectors

Purchases are between you and the artist. Mostra issues a certificate of authenticity for each sale. Disputes about shipping, condition, or refunds are resolved with the artist first.

6. Content rules

No hate, no harassment, no impersonation, no stolen work, no illegal goods. We can remove content and accounts that break these rules.

7. Liability

Mostra is provided as is. We do our best to keep the platform up and your data safe, but we cannot promise it will be perfect.

8. Changes

We may update these terms. If a change is material, we will let you know in advance by email or in the app.

9. Governing law and jurisdiction

These terms are governed by the laws of England and Wales. Any dispute is subject to the exclusive jurisdiction of the courts of England and Wales.

10. Legal entity

Mostra is operated by House of Octopus Limited, a company registered in England and Wales under company number 17228856, with its registered office at 6 Boulevard Place, Apartment 137, Hove, BN3 7RR, United Kingdom. Contact: hello@getmostra.com.
