Privacy policy

Last updated 15 November 2026

dhyan is a planning and focus app for Android and Mac, made by AR Coding ("we"). This policy explains what dhyan collects, why, and what control you have. The short version: your plan is encrypted on your own devices, we can't read it, and we never sell or share your data or show ads.

Your account

You sign in with your Google account through Firebase Authentication. We receive your Google account's email address, name and a unique account ID, and use them only to sign you in and keep your devices connected to the right account.

Your plan is end-to-end encrypted

Goals, tasks, focus sessions, schedules and day and week plans are encrypted on your device with your own account key before they are synced. Our servers store only the encrypted data and the times it was created, changed or deleted. The key never leaves your devices, so neither we nor Google can read your plan.

To check that a device holds the right key, we keep a short check value derived from it. The key can't be worked out from this value.

Your devices

For each phone or Mac you link, we store its name, operating system and app version, when it was last seen, its public key, a push-notification token and the sharing settings you chose for it. We use these to link your devices, send them updates and let you see and remove them.

Recovery and backups

• 12 recovery words. dhyan shows you 12 words that can restore your key. We don't keep a copy.
• Backup file. If you save a backup, dhyan creates a file locked with a password you choose and keeps it on your phone and in its Downloads/dhyan folder. The password never leaves your phone.
• Google Drive. If you choose to, the same password-locked file is also saved in Google Drive's hidden app data folder. dhyan asks only for access to that folder; it can't see or change your other Drive files. The file uses your Drive storage, and you can remove it from Drive settings under "Manage apps".

Focus and app blocking

To rest the apps you chose during a focus session, dhyan uses Android's Accessibility service and related permissions to notice which app is open. It never reads what's on your screen. The name of the open app is used only on your phone and is never sent anywhere. dhyan keeps only a count of how many times a resting app was covered, encrypted with the rest of your plan.

Features you turn on for a linked Mac

You can choose to show one-time codes from text messages, incoming calls, notifications or your clipboard on your linked Mac. Each is off until you turn it on, and asks for its permission only then. This information goes directly from your phone to your Mac over your local Wi-Fi network, encrypted between the two devices. It is never sent to our servers and never stored by us.

Camera

The camera is used only to scan the QR code that links your Mac. Images are processed on your phone and are not saved or sent anywhere.

Who processes data for us

dhyan runs on Google Cloud and Firebase (Authentication, Cloud Firestore, Cloud Messaging and Cloud Run). Google processes data on our behalf under its own terms. We use no advertising or analytics services, and we don't sell, rent or share your data with anyone else.

Security

All data is encrypted in transit. Your plan is also encrypted with a key only your devices hold, and backups are locked with your password. Access to your account's data is limited to your signed-in devices.

Keeping and deleting data

• If you choose "Start fresh" on a new phone, your old encrypted data is set aside for 30 days, in case you find your recovery words, and then deleted.
• You can remove a linked device at any time from the app.
• To delete your account and all its data, email us at the address below from your account's email address. We delete it within 30 days. Backup files on your phone or in your Google Drive are yours, and you can delete them yourself at any time.

Children

dhyan is not directed at children under 13, and we don't knowingly collect data from them.

Changes

If we change this policy, we'll update the date above. If a change affects how your data is used, we'll tell you in the app first.
