Privacy
Last updated: 11 November 2026
Kasa collects no data from you. Your rows, accounts and statements stay on your phone, inside Kasa; we never see them.

What stays on your phone
The rows you add, your accounts, categories, rules and the card statements you load are kept only in Kasa's database on your phone. A statement you load is read on the phone; the PDF is sent nowhere.
Kasa has no sign-up and no sign-in. It contains no analytics, advertising or crash-reporting tools.
The only thing that goes online: exchange rates
While Ayarlar → Genel → Canlı kur (live rates) is on, as it is at first, Kasa downloads the current exchange rates at most once a day from the European Central Bank (ecb.europa.eu) and ExchangeRate-API (open.er-api.com). These requests carry nothing about you; like any web request, they show those sites your phone's IP address. With live rates off, Kasa never goes online and you type the rates yourself.
Backups and exports
A backup is one file, encrypted with the backup passphrase you choose. With automatic backup on, the latest backup is saved to your own iCloud Drive, where Apple's iCloud terms apply. The passphrase is kept only on your phone; we cannot see it, and a backup cannot be opened without it.
You decide where the CSV and JSON files you export are sent.
Purchases
The 14-day trial and the unlock are bought through the App Store. Kasa never sees your payment details; it reads only the purchase record Apple has verified. Apple's own privacy policy applies.
Lock and notifications
With Kilit (lock) on, Kasa asks your phone to confirm it is you as it opens: Face ID, Touch ID or the phone's passcode. Your face, fingerprint and passcode stay with the phone; Kasa learns only whether the check passed.
Reminders are local notifications set on the phone; they do not come from a server.
Deleting your data
Ayarlar → Tüm verileri sil (erase everything) deletes your rows, accounts and statements from the phone. Deleting the app deletes Kasa's database too. You can delete the backup in iCloud Drive from the Files app.
When you write to us
If you email us, your address and message are used only to answer you and are shared with no one. The app's Bize yaz (write to us) adds Kasa's version, your phone's system version and, when a statement could not be read, the error code and the statement layout's name to the email; you see them before sending and can remove them. Please do not send statements or account details.
