Horizn is an offline-first personal budgeting app. Your data stays on your device — there are no accounts and no sign-in. This page explains how to get help.

The entity responsible for the app:

  • Sławomir Dyduch, sole proprietor (Polish jednoosobowa działalność gospodarcza)
  • Mazańcowice 73, 43‑391 Mazańcowice, Poland
  • Tax ID (NIP): 9372581357 · REGON: 243568459
  • Formal matters and data protection: info@horizn.world

When you write, please include:

  1. Your device model and iOS version.
  2. What you expected to happen and what happened instead.
  3. Your installation identifier (SID) — the short code at the bottom of the Settings screen (for example HRZN-AB12-CD34). It helps us understand your report and contains no personal data.

We never ask for your PIN, your financial data, or a copy of your budget. You don't need to send any of that to get help.

Frequently asked questions

How do I back up or move my data? Everything is stored on this device and is included in your system device backup (e.g. iCloud), so it moves to a new phone along with your backup. You can also use Import data to load a CSV file or a bank statement.

I forgot my PIN. On the lock screen choose to reset the PIN; you'll confirm your identity with Face ID (if enabled). For security, there is no remote recovery — Horizn has no account.

How do I restore my Premium subscription? Open the Premium screen and tap Restore purchases. Use the same Apple Account you bought it with. To manage or cancel the subscription, go to https://apps.apple.com/account/subscriptions.

How do I import a bank statement or a CSV? Profile → Import data. A standard CSV import is free; dedicated bank imports (mBank, PKO BP, ING, Santander) are a Premium feature. The screen shows the exact CSV column format.

How do I delete everything? Profile → Danger zone → Delete all data. This permanently erases all data on the device, including your PIN and encryption key. It cannot be undone.

Which permissions does the app need, and why? Camera and Photos — only to attach a picture to a transaction. Face ID — only to unlock the app or reset your PIN. Notifications — only for local reminders. You can change these anytime in iOS Settings.
