TaskNote uses client-side encryption. Your notes, tasks, and reminders are encrypted on your device before they are stored or synced. The encryption key is created on your device on first use and never leaves it. TaskNote cannot read your content because it does not have your key.
This strict privacy model means you are solely responsible for your key. There is no password reset for your data.
TaskNote encrypts everything related to your content on your device:
This means the server stores only encrypted blobs of data.
When you write or edit something, TaskNote encrypts it locally on your device. Only the encrypted version is stored and synced.
Decryption happens only on your device, using your key.
Your key is generated on your device on first use. You can save it wherever you want (e.g., a password manager, encrypted drive, or offline storage).
The key is never uploaded to the server. TaskNote does not keep a copy.
If you lose your key, you lose access to your encrypted content.
There is no recovery email, and there is no reset that can decrypt existing data. This is intentional. If the service could recover your notes, it would mean the service could access your notes (a "backdoor").
Many note apps prioritize convenience with recovery flows that require server-side control (meaning they technically hold the keys to your data).
TaskNote prioritizes privacy by design. The tradeoff is simple: You must keep your key safe.
Yes. Titles and folder names are encrypted on your device.
Yes. Tasks and reminders are encrypted the same way as notes.
No. The key is created on your device and never sent to the server.
No. TaskNote does not have your key, so it cannot decrypt your content.
You lose access to the encrypted content. There is no recovery, by design.
