Privacy Policy.

What we collect

• Account info — the Sui wallet address you sign in with. We never see or store a wallet’s private key.
• Content you create — notes, tags, cabinets, and their timestamps. Notes flagged Private are kept out of Walrus backup and semantic search and are never synced to our shared memory store — they live only in our Convex database. You can optionally back up a Private note with per-wallet client-side encryption (encrypted in your browser, decryptable only by signing with your own Sui wallet); until you turn that on for a note, it’s stored in Convex the same way as any other note, just never backed up externally.
• Payment records — if you pay by card, Stripe handles and stores your payment details directly; we only keep a customer/subscription reference and invoice history, never your card number. If you pay with USDC on Sui, we read the public transaction from the Sui blockchain to verify it — that transaction is public on-chain regardless of us.
• Basic usage data — things like when you signed up, your current plan, and which notes are backed up to Walrus, so the app can show you accurate status.
