Farthing · Effective date: September 8, 2026 · Last updated: November 14, 2026

Farthing (bundle identifier xyz.bogtsi.farthing) is made by Bogdan Tsiganiuk, an individual developer. Contact: bogdan.tsiganiyk@gmail.com.

What we collect

Farthing has no bank connection, advertising SDK or identifier for advertisers (IDFA). We do not use data for tracking across other companies' apps or websites for advertising. Third-party service providers process purchase information and app-update metadata and diagnostics as described below. If you email support, we receive your email address and the information you choose to send; please do not include sensitive budget records unless needed for your request.

What stays on your device

• Your settings: pay rhythm, currency, locale, appearance, lock and notification preferences.
• Your pots: name, kind (Bills, Spending or Savings), planned amount, rollover rule, and any savings goal and target date.
• Your incomes: name and expected amount.
• Your cycles: each pay period's allotments, what carried over from the last one, and what each income actually paid.
• Your transactions: every spend, income entry and transfer between pots, with its date and an optional note.

These records are written to your device's local app storage; Farthing uses no cloud budget database of its own. Deleting the app removes its local budget records, but does not delete exported files, device backups or service-provider records.

When data leaves your device

1. You export a file. Tapping Export backup or Export CSV in Settings → Backup & restore builds a file and hands it to the iOS share sheet. Where it goes from there is your choice — Files, iCloud Drive, Mail, another app. We are not involved and we receive no copy.
2. Device backups. Depending on your iOS backup settings, app data may be included in an iCloud or computer backup. These copies are managed by you and Apple, not by Farthing. Farthing does not implement its own budget sync.
3. Purchases and purchase status. Apple processes payment; we do not receive your payment-card details. RevenueCat manages purchase validation and Pro access using an anonymous app-user identifier, purchase receipts and purchase history. This also supports purchase analytics in RevenueCat's dashboard. Farthing does not send budget records as part of purchase processing. See RevenueCat's privacy policy.
4. App updates and launch diagnostics. Expo Update receives a random per-installation client identifier, your IP address, platform and runtime information, and update identifiers when checking for or downloading updates. After a failed launch, requests can also include failed-update identifiers and the last fatal launch error text (up to 1,024 characters, sent once). Expo uses these records to deliver updates, measure installation and update usage, and diagnose failed launches. Expo retains launch error text in raw request logs for three days. Error messages may contain information present when an error occurs; we cannot guarantee they will never contain user-entered information. Farthing does not add budget records to update request headers or extra parameters. Expo states that it does not derive location from these requests or use this data for advertising or tracking. See Expo's update privacy documentation and privacy explanation.

RevenueCat and Expo service requests use HTTPS. This protects data in transit, but no storage or transmission method can be guaranteed completely secure.

Notifications and Face ID

If you turn on pay-day or bill-due reminders in Settings, Farthing schedules them locally on your device using iOS's own notification system. Nothing is sent to a server to make this happen, and the app has no push-notification capability at all. If you turn on the Lock setting, Farthing asks iOS to check your face or passcode using Face ID / device authentication; Farthing never sees or stores any biometric data itself — that stays entirely within Apple's own secure system.

Children

Farthing is not directed at children. The service-provider processing described above can occur regardless of the user's age. If you believe a child has provided personal information through Farthing or support, contact us so we can review the request and available steps.

Your rights

You can export your local budget records or erase them using Settings → Backup & restore, or remove local records by deleting the app. Manage exported files and iCloud or computer backups separately. These actions do not erase Apple purchase history, RevenueCat purchase records or Expo request records. Depending on your location, you may have rights to access, correct or request deletion of personal information. Contact bogdan.tsiganiyk@gmail.com about privacy requests; we will review what information we or our service providers can identify and what applicable law requires. Because Farthing has no account and uses anonymous service identifiers, we may need additional information to locate a record. Please do not send your budget backup merely to identify yourself.

Changes

If this policy changes, the date at the top changes with it, and the version in the app's Settings → Support & legal links to the current one.
