Frequently asked questions.
- Do you store my JSON on a server?
- No. Pro snippets are encrypted in your browser before they leave it. The server holds opaque ciphertext blobs that nobody — not even us — can decrypt without your passphrase.
- What happens if I forget my passphrase?
- You generate a recovery key when you set up the vault. Save it somewhere safe (printed, password manager, etc.). With the recovery key you can still unlock. Without either, the snippets stay encrypted forever — we cannot reset them.
- Is this a subscription?
- No — and that's the point. You pay $1, you get Pro for 30 days. When the 30 days are up, Pro stops. We never auto-charge your card. If you want another month, come back and pay again.
- What does the $1 promo cover?
- Launch promotion. The normal monthly price will be $5; right now any 30-day pass costs $1. Stack passes if you want — each new purchase extends the window by 30 days from whichever is later (today or your current expiry).
- What happens to my snippets when Pro expires?
- They stay encrypted in the cloud and on your devices, but the cloud sync turns off — you can still read everything saved locally and you can buy another 30-day pass at any time to resume syncing.
- I'm on a team. Is there a team plan?
- Not yet. The data model is built to support team accounts — invitations, shared snippet libraries, an audit log — but the tier itself ships later. Email us if you want early access.
