Privacy Policy

1. No account, no server

Zetta Quota has no account and no login, and ZettaByte runs no server for it. We do not collect any personal data, and we cannot see anything you enter in the app.

2. What the app stores on your device

Everything you enter is kept in a local database on your phone, and nowhere else:

• Cards: a nickname, the last 4 digits, the expiry month and year, and the options you tick for each card
• Payments: amount, currency, date, status, the card used, the exchange rate used and any note you add
• Trips: name, countries, currency and dates
• Settings: your yearly limit, its currency and reset date, your bank and the app theme

The app never asks for or stores a full card number, CVV, PIN, one-time password, bank login or bank statement. The last-4 field accepts exactly four digits.

3. Network use: exchange rates only

The only network calls the app makes download public exchange rates:

• open.er-api.com (the main feed)
• the fawazahmed0 currency-api, served through jsDelivr or its pages.dev mirror (the backup feed)

These requests ask for the current US dollar rates and send no personal data: nothing about you, your cards or your payments. The services can see the ordinary technical details of any web request, such as your IP address, under their own policies.

4. No analytics, ads or tracking

Zetta Quota contains no:

• Analytics or usage tracking
• Crash reporting
• Advertising or ad networks
• Tracking or third-party SDKs that collect data

5. Backups

A backup is a file you create yourself and send through your phone's share sheet, to wherever you choose. We never receive it. Anyone you share the file with can read the data in it, so keep it as you would any personal record.

6. Deleting your data

Use "Delete all data" in the app’s settings, or uninstall the app. Either removes everything the app stored on your phone. Backup files you saved elsewhere are yours to delete.

7. Sharing and selling

We do not sell, share or transfer any data. We do not have any to sell, share or transfer.

8. Children's privacy

Zetta Quota is not directed at children under 13, and we do not knowingly collect information from them. The app collects no personal data from anyone.

9. Changes to this policy

If this policy changes, the new version will be posted on this page with a new effective date.
