Privacy
Last updated: 16 October 2026.
Canvas64 has no accounts. The interface never asks for your name, e-mail, phone number or any identity document, sells no personal data, shows no advertising of its own, and uses no analytics or tracking cookies.
Public on the chain
Every purchase, payment and owner's wallet address is recorded on Base, a public blockchain, by the contract. Anyone can read that record, permanently, and nobody, including us, can change or delete it. Requests to erase or correct data cannot apply to the blockchain.
What the interface keeps
| What | Why | How long |
|---|
| Your profile: nickname, avatar, photo reference, links and the time you signed it | To show it on your cells | Until you change it; it is public by design |
| A photo you upload | To screen it and show it | Not shown: deleted within 7 days. Shown: kept while on your profile, then deleted within 90 days |
| A report of a cell, as a one-way fingerprint that cannot identify the reporter | To count reports from different visitors once | 90 days |
Your wallet's signature proves a profile is yours; it is verified and used for nothing else.
How we use it
Only to run the interface: to show the wall and profiles, to screen photos against the content policy, to handle reports, and to keep the interface secure and available. Photos are screened automatically and are never used to train models or shared for any other purpose.
Service providers
The interface runs on infrastructure providers for hosting, content delivery, storage and automated screening, and reads the blockchain through public network endpoints. They process technical data such as network addresses and requests to deliver and protect the service, and they may do so in several countries. Your wallet and any wallet connector you choose are governed by their own policies.
In your browser
The site keeps two small items in your browser's storage, never sent to us: that you accepted the ownership terms of a purchase, and which wallet you last connected, so it can reconnect. Clearing your site data removes them.
Security
We keep stored data to the minimum above and protect it with the safeguards of our providers. No system is perfectly secure, and the blockchain is public by design.
Your choices
- Change or remove your nickname, photo and links at any time; the old ones stop showing at once.
- Disconnect your wallet in the account.
- For any other request about data the interface keeps, write through the Report this cell button on the cell's card.
Third parties
Links on cells lead to services we do not control; their own policies apply.
Children
The interface is for adults only. Do not use it if you have not reached the age of majority where you live.
Changes
We may update this policy; the date at the top shows the latest version.
