What the App Does

When you add a subscription's name, price, billing cycle, billing date, reminder day, and notes, the app calculates your next billing date and monthly spending within the app.

Good to Know

Amounts and billing dates in KokKok are estimates based on the values you enter. The app does not check whether a payment actually went through, and it does not cancel subscriptions on your behalf.

Data Storage

Your subscription information is stored on your device. App data is deleted when you use "Delete all subscriptions" in the app's Settings or delete the app. Depending on your operating system's backup and restore settings, device data may be backed up.

Does the app cancel my subscriptions?

No. The app can record a planned cancellation date and exclude the subscription from later calculations, but you need to cancel each subscription directly with the service itself.

Does it read my actual payment history?

Not by default. Calculations are based on what you enter. The app never connects to card or bank accounts or reads your text messages or email.

On Android, if you turn on the optional "Card payment notification detection" and agree, the app analyzes on your device only new payment notifications from the card or bank apps you choose and suggests subscription candidates. Notification text is never stored or sent off your device, and nothing is added until you review and save it.

What happens to photo icons?

A photo you choose from your photo library is copied into the app's private storage. When you delete data in the app, the icon files the app copied are deleted, but the original photos in your library are not.

Exchange Rate Source

To convert subscription prices in other currencies into your base currency, the app uses the latest business-day exchange rates (USD-based) from the Frankfurter v1 public API. Frankfurter aggregates public reference rates from central banks and official institutions, and its v1 latest rates are updated daily on business days.

ECB statistics may be reused for commercial and non-commercial purposes, provided the source is acknowledged and the statistics are not modified. Currency conversion in KokKok is an estimate provided for reference to help you understand the amounts you enter.
