Something not working?
A real person answers this, usually the same day. There is no ticket system and no bot.

Common problems
My notes are not syncing
Sync needs the Cloud plan and an account signed in on both devices. Check your account page — it lists every device that has connected and when. If the plan says Free or Pro, sync is off by design.
The keyboard shortcut does nothing
Another extension has probably claimed it. Open chrome://extensions/shortcuts and set a different one.
My voice note has no transcript
Transcription needs Pro or Cloud, and it runs after the note is saved — give it a few seconds and pull again. Encrypted notes are never transcribed: the server cannot read them, which is the point of the setting.
I forgot my encryption passphrase
Then those notes cannot be recovered, by you or by us. That is what end-to-end encryption means, and it is the trade you accepted at the switch. Notes on a device you are still signed in to remain readable there — export them (Settings → Export) before signing out.
I want my data
Export to Markdown or PDF from the app at any time, no account required.
I want my account deleted
Do it yourself on the account page — it deletes the account, every note and every attachment immediately, with no waiting period and no email confirmation loop. Or ask us on WhatsApp and we will do it.
Refunds and cancellation
Where you bought it decides who refunds it:
- On this website (PayPal): message us on WhatsApp. Cancel any time from your account; access runs to the end of the period you already paid for.
- Inside the iPhone or iPad app: Apple handles it — request a refund from Apple, and manage or cancel the subscription in Settings → your name → Subscriptions.
- Inside the Android app: Google handles it — request a refund from Google Play.
We cannot cancel or refund a subscription that Apple or Google is billing. Neither store gives a developer that ability.
Reporting a security problem
Message the WhatsApp number above with “security” in the first line and we will reply before anything else in the queue. Please do not post the details publicly until it is fixed.
