Your data & choices

Last updated · September 28, 2026

Understand where your records live and what happens when you change them.

You choose what to record

TellyNest stores the entries you manually provide. There is no bank connection or automatic bank-statement import. Only add information you are entitled to store.

Cloud and device storage

Account information and financial records are stored using Supabase, currently in Tokyo, Japan. Your device stores session information so you can stay signed in. Signing out does not remove cloud records.

Editing and voiding entries

You can edit records and void entries in the app or web workspace. Voiding removes an entry from balance calculations but retains its underlying record. This is different from permanent deletion.

Account deletion and export

Open Profile → Delete account in the app, or Account → Account security in the web workspace, and confirm permanent deletion. This removes your account, owned books, entries, custom types and membership records. This action cannot be undone. It does not cancel Apple or Google subscriptions; manage renewal separately in your store account. Uninstalling the app does not delete your account. Data export is not currently available.

Membership changes

Changing or ending a membership does not erase past financial records. Currency allowances apply to new records according to the current membership period.
