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.
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.
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.
Paid plans renew automatically until cancelled. You can cancel at any time from your account. Refunds for unused time are handled case by case.
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.
No hate, no harassment, no impersonation, no stolen work, no illegal goods. We can remove content and accounts that break these rules.
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.
We may update these terms. If a change is material, we will let you know in advance by email or in the app.
