Tally

Tally records border crossings and counts the days you spend in each country.
Add a country and entry date; the next crossing closes the previous stay, and
every affected total updates when you correct a visit.

Saved rules turn the log into days counted, days remaining, and projected
threshold dates. Tally supports calendar and tax years, rolling windows,
consecutive stays, multi-year tests, Schengen 90/180, CA-4, permits, and
personal limits where the recorded inputs are sufficient.

Each result includes its rule profile, source, version, retrieval date, and
calculation boundary. Profiles that need more facts or review remain visible
with their recorded totals and can use a personal planning limit.

Travel data and arithmetic stay on the device in an encrypted SQLCipher
database. Optional app lock uses biometric or device-credential authentication.
Passphrase-encrypted backups move through Android's system file picker.

Tally is MIT licensed. Its calculations help you track recorded days; consult
the cited source and qualified advice for legal or tax decisions.
