Privacy Policy — MyFinance
Last updated: 6 June 2026 · Contact:

MyFinance ("the App") is a personal finance tracker. This policy explains what
data the App handles and how. We do not sell your data and we do
not use advertising or analytics tracking.
1. Data we handle
- Financial data you enter — transactions, accounts, categories,
budgets, goals, notes and tags. This is the core content of the App.
- Account data — if you sign in with Google, we receive your
Google account email, display name and profile identifier (UID) to enable
cloud sync.
- Authentication — an optional PIN and/or account password.
These are stored on your device in hashed form (SHA‑256 with a random salt);
we never store them in plain text and never transmit them.
2. Where your data is stored
- On your device — by default all financial data is stored
locally in a private database on your phone.
- Cloud sync (optional) — only if you sign in with Google,
your financial data is synced to Google Firebase (Cloud Firestore) under your
personal account space (
users/<your‑id>). Security rules
ensure that only you can read or write your own data.
- Backup (optional) — you may back up data to your own Google
Drive (private app‑data folder). Only you can access it.
3. Third‑party services
- Google (Sign‑In, Firebase Authentication, Cloud Firestore,
Google Drive) — provides authentication and cloud sync.
See Google Privacy Policy.
- EmailJS — used only when you contact support from within the
App; it sends the name and message you provide so we can reply.
- Exchange‑rate API (
open.er-api.com) — fetches
public currency rates. No personal data is sent.
4. How we use the data
Solely to provide the App's features: recording and displaying your finances,
syncing them across your devices when you choose to sign in, and answering your
support requests. We do not share your data with anyone except the service
providers listed above, who process it only to deliver these features.
5. Data retention and deletion
You are in control of your data at all times:
- Delete your local data from inside the App (Settings → Data → Clear all data).
- Sign out to stop cloud sync.
- Uninstalling the App removes all local data from your device.
- To request deletion of your account and cloud‑synced data, email
kapanov.adil@gmail.com and we will
remove your data from Firebase associated with your account. See our
account & data deletion page for details.
6. Security
The App supports a PIN and device biometrics to protect access. PINs and
passwords are stored hashed with a per‑user salt. Cloud data is protected by
per‑user Firestore security rules. No method of storage or transmission is 100%
secure, but we take reasonable measures to protect your information.
7. Children
The App is not directed at children under 13 and we do not knowingly collect
data from them.
8. Changes
We may update this policy. Material changes will be reflected by the "Last
updated" date above.
