Lunara

Lunara helps you track your period and cycle privately. Your entries stay on this device, there is no account, no ads or tracking, and backups are files you control.

Privacy

Your cycle data stays on this device unless you choose to move it.

See what stays on your device, what Lunara does not collect, and what you should back up yourself.

Your period dates, symptoms, notes, and cycle history stay on the device and browser you use.

There is no account, no ads or tracking, and backups are files you choose to create and keep.

Lunara is not medical, legal, or emergency guidance.

At a glance

Lunara lets you track period dates, symptoms, notes, and cycle history without creating an account. Your saved tracker data stays on the device and browser you use.

Lunara does not use ads, analytics, or third-party tracking scripts. It also does not create a cloud account that quietly copies your cycle history elsewhere.

What stays on this device

Your saved tracker data stays on the current device and browser unless you choose to export a backup file or enter the data somewhere else.

Closing Lunara does not erase your saved tracker data. Clearing site data, clearing website data, changing browser profiles, resetting the browser, or replacing your device can remove it.

Before you make those changes, create a password-protected backup and make sure you know the backup password.

How access works

You create a 4 to 6 digit PIN during setup. That PIN opens Lunara on this device. After setup, you can add an optional passphrase while keeping PIN unlock available.

Refreshing the page or closing the app returns Lunara to the lock screen, so the next visit asks for your PIN or passphrase again.

A passphrase is not an account recovery path. Lunara cannot recover a forgotten PIN or passphrase for you.

Safety PIN

A safety PIN is optional. Some people may find it useful in coercion or privacy-risk situations where someone may be pressuring them to unlock the app; many people do not need it.

If enabled during setup, the safety PIN opens a separate empty-looking space. It does not recover the real tracker, hide real data, sync data, contact anyone, or replace emergency or legal help.

What can remove local data

Browsers do not always label saved website data the same way. In many cases, clearing cookies and site data, clearing website data, or removing saved storage for Lunara can remove your tracker data.

Clearing browsing history alone usually does not remove your tracker data, but Lunara does not rely on that distinction as a safety guarantee. If you plan to reset the browser, clear website data, change browsers, or move devices, create a backup first.

Lunara has no account recovery path if your saved tracker data and backups are gone.

Backups, export, and restore

Backups are files you create and download to a place you choose. The recommended option is password-protected because it is safer if someone else finds the file.

Plain backup files and readable exports can be useful, but they are not the safer default because someone with the file may be able to read the contents.

When you restore a backup, Lunara checks the file first and then uses it to replace the current tracker data. Restore does not merge two histories together.

Supporter payments stay separate

If you choose the optional supporter checkout, Stripe processes the payment and receipt flow separately from Lunara's tracker data.

Lunara does not send cycle entries, notes, symptoms, or backup content to Stripe. The tracker still does not require an account, ads, analytics, or third-party tracking.
