A little help
Help & support
Questions, feedback, or a bill that needs a second look?
Email support ↗Can I use it without AI?
Yes. Manual entry and the main ledger do not require a language model. Scanning uses bundled on-device text recognition and rules. A compatible, already-available system model may assist; it is optional.
What if a scan misses a detail?
Compare the source text, correct the fields, and confirm the item before adding it. If there is no useful suggestion, choose Add entry and fill it in yourself. Scanning does not automatically import, charge, or cancel anything.
Where are my records?
On your device. Export a JSON backup before moving to another phone. JSON includes bill history; CSV contains subscription information. Keep backups somewhere safe. Uninstalling or clearing app storage can remove your local records.
Why was a reminder late?
Android may delay reminders to conserve power. Check notification permission and your phone’s battery settings. Reminders are helpful prompts, not guaranteed alarms.
Is Lunar Ledger on Google Play?
The Android release is being prepared. We will add an official download link here when it is available. There is no sign-up or payment form on this website.
How do I change language?
In the app, open Settings → Language and choose English or 简体中文. On the website, use the language link in the header. English is the default. Your subscription names and notes keep their original text.
When contacting us
