Privacy Policy
Last updated: 2026-08
What we collect
Account info (email / username / nickname), the board content you create (schematic, layout and fab package), uploaded assets, and your conversations with the AI assistant. We do not collect full card numbers, CVVs or payment passwords.
How data is used
Only to save, publish and manage the boards you create, to decide who can open a board's share page according to the access mode you set, and — when you ask for it — to have AI generate or edit content. We do not sell your data or use it for advertising.
How data is protected
Account passwords are stored as salted Argon2 hashes, never in plaintext; sessions use expiring JWTs, and changing your password or signing out invalidates old credentials.
Retention and deletion
You can delete your projects; account-deletion requests can be submitted by email and remain subject to necessary security, backup, audit and legal retention periods (soft-deleted accounts are hard-deleted after the period).
Third parties
If you choose to sign in with your Tutu account (tutuid), that flow follows its privacy policy. When you use AI features, the content you submit is sent to the Tutu AI service for processing; visitor analytics for published boards are handled by Tutu Analytics, which does not store visitor IP addresses in plain text. TutuPCB is a member of the Tutu suite, and your sign-in identity is federated across the suite.
