Fairzo privacy policy

The short version. Fairzo has no account and no server of its own. What you type into it stays on your phone. We never receive your expenses, your friends' names or your balances, so we can't sell or share them. The app has no analytics, no advertising and no tracking. The only thing it downloads is exchange rates, and that request contains no information about you.

1. Who we are

Fairzo is made and published by DevEntia Tech (Private) Limited, a company registered in Pakistan (“DevEntia Tech”, “we”, “us”). Our postal addresses are in section 15. For any question about privacy, email [email protected].

2. Who this policy covers

This policy covers the Fairzo app for iPhone and Android.

It doesn't cover this website. deventiatech.com, including these Fairzo pages, is covered by DevEntia Tech's website privacy policy. The website uses Google Tag Manager to load website analytics (such as Google Analytics), which measure visits to its pages, including clicks on the buttons on these pages, and may set cookies in your browser. That happens on the website only. The app contains no analytics and sends nothing to Google Tag Manager.

3. What the app stores, and where

Fairzo saves what you enter in a database inside the app's private storage on your phone:

• Expenses: amount, currency, title, note, category, date, who paid, and how the cost is split.
• Payments you record: amount, currency, method (such as cash or bank transfer), date and note.
• People: the names you give your friends, and your own name if you entered one. No phone numbers, emails or contacts are read or stored.
• Groups: name, type and members.
• Reminders: the time and text of reminders you set.
• Activity history: a list of changes you made, so you can see them and restore deleted items.
• Settings: your main currency, theme and reminder time.
• Exchange rates: rates downloaded for the dates you used.

We don't have a copy of any of this. Nothing in this list is sent to us or to anyone else, except in the cases in section 4, which you start yourself.

The app reads your phone's language and region settings to suggest a main currency and to format numbers and times. This happens on the phone and isn't sent anywhere.

4. What leaves your phone

Exchange rates. When you use a currency other than your main one, the app downloads exchange rates from api.frankfurter.dev, a free public service run by an independent open-source project, not by us. The request contains:

• the list of currency codes the app supports, which is the same for every user;
• for a past date, that date (the date of an expense you entered in another currency).

It contains no amounts, names, notes or device identifiers. As with any connection to a website, the service receives your IP address, the time of the request and basic technical details of the connection. Frankfurter states that its API “doesn't collect or log personal data, IP addresses, or request URLs”, and that it runs behind Cloudflare for caching and protection against attacks (frankfurter.dev). These servers may be outside your country. We receive nothing from this request apart from the rates. Each date's rates are saved on your phone, so a date is downloaded only once.

Things you choose to share. Three features open your phone's share menu: Export to CSV, Share summary (a group's balances) and Ask to pay (a message to a friend). The file or message goes only to the app or person you pick, and the app you pick handles it under its own privacy policy. We don't receive a copy. The CSV file is written to a temporary folder on your phone first.

Emails you send us. If you tap Contact support, your email app opens a message to us. When you send it, we receive your email address, your message and the app version in the subject line. We use them only to answer you.

Ratings. If you rate the app, the rating prompt and your review are handled by Apple or Google.

Links. Links to this page, the terms, the exchange-rate provider and the app store open in a browser or the store app. Those sites have their own privacy policies.

Crash reports. If you have chosen in your phone's settings to share diagnostics with app developers, Apple or Google may send us crash reports. These don't contain your expenses or the names you entered.

5. Phone backups

Your phone's own backup can include the app's database:

• iPhone: iCloud Backup, if it is turned on, follows Apple's terms and your iCloud settings.
• Android: Android backs up app data to a private area of your Google account, if backup is turned on. On Android 9 and later with a screen lock, Google encrypts this backup end to end (Android developer documentation).

These backups belong to your Apple or Google account. We can't access them. When you install the app again on a phone that uses the same account, your data can come back from the backup. Backups don't move data between iPhone and Android, so use Export to CSV to keep a copy when you switch.

6. Notifications

Reminders are optional: a daily reminder, and settle-up reminders you set for a friend on a day you pick. The app asks for permission to show notifications only when you turn on a reminder. Your phone schedules and shows reminders itself. The app uses no push service and creates no push token, and nothing about your reminders leaves your phone. You can turn reminders off in the app (Settings, Reminders) or in your phone's settings.

7. Permissions

• iPhone: notifications, and only after you turn on a reminder.
• Android:
  • internet access, for exchange rates;
  • network status, to tell when you're offline;
  • notifications, asked for only after you turn on a reminder (Android 13 and later);
  • run at startup, so reminders survive a restart;
  • wake lock, to deliver a reminder on time;
  • vibration, for the small vibration when you save.

The app doesn't ask for your contacts, location, photos, camera, microphone or files.

8. Why this is lawful (for users in the EU and UK)

• The data in the app is stored and processed on your phone, by you, for your own records. We don't receive it.
• When you email us, we use your email to answer you. Our legal basis is our legitimate interest in giving support (GDPR Article 6(1)(f)).
• We don't sell personal data or use it for advertising, profiling or automated decisions.

9. Security

Your data sits in the app's private storage, which other apps can't read. It is protected by your phone's screen lock and the encryption your phone provides. We recommend you set a screen lock. Exchange-rate requests use an encrypted connection (HTTPS).

10. How long data is kept

• On your phone: until you delete it.
  • Deleted expenses, payments and groups stay restorable for 30 days and are then removed.
  • The activity history keeps changes from the last 30 days and the latest 500 entries.
  • Delete all data removes everything you entered.
• Support emails: for as long as we need to answer you, and no longer than 24 months.

11. Deleting your data

In the app, open Settings (tap your initial at the top of Home), then tap Delete all data. This erases your expenses, payments, friends, groups, reminders, activity and profile on this phone, and cancels the reminders. It keeps only your theme choice and the downloaded exchange rates, which contain nothing about you.

Uninstalling the app also deletes its data. Copies can stay in older iCloud or Google backups until those are replaced or deleted in your account settings.

Because we don't hold your app data, there is nothing for us to delete on our side. To have your support emails deleted, write to us.

12. Your rights

Depending on where you live, you have the right to:

• access, correct or delete personal data we hold about you;
• object to or restrict how we use it;
• receive it in a portable format.

For the data in the app, you can do all of this yourself: view and edit it, export it to CSV, or delete it. For anything we hold, such as support emails, write to [email protected]. You also have the right to complain to your local data protection authority.

13. Children

Fairzo is not directed at children under 13, and we don't knowingly collect personal data from anyone, including children.

14. Changes to this policy

If we change this policy, we'll update this page and the effective date at the top. If a future version of Fairzo would send any of your data somewhere new, for example to sync between phones, show ads or sell an upgrade, we'll update this policy and say so in the app before that version collects anything.
