How Budget Lock Compares
The honest version
Budget Lock is a small offline app. Our one specific advantage: your financial data never leaves your phone. This page shows what that means compared to typical server-based budget apps.
Contents
1. At a glance
| App | Account required | Data sent to a server | SMS auto-read | Bank linking | Pricing |
|---|---|---|---|---|---|
| Budget Lock | No | None (your transactions never leave your phone) | No | No | Free + one-time Remove Ads IAP |
| Typical server-based budget apps | Yes | To remote servers | Some | Many (via aggregators) | Subscription or freemium |
Most server-based budget apps require an account and use generic encryption claims. Budget Lock requires no account and publishes its full algorithm stack — see Security.
2. Privacy & data collection
Typical server-based apps collect
Email, password, name, postal address, phone, device fingerprint, IP, ad IDs, cookies, linked-bank balances and transactions, uploaded receipts. Some also collect SMS content, GPS, and government IDs.
Budget Lock collects
None of the above. No account, no bank linking, no SMS, no GPS. Free-tier ads use AdMob (disabled by the Remove Ads purchase).
3. Encryption
| App | Encryption claim |
|---|---|
| Typical server-based budget apps | SSL/TLS in transit; generic "256-bit" or "bank-grade" claims. |
| Budget Lock | AES-256 on-device, with the password-stretching, sub-key, and tamper-check details published. |
See the Security page for the full details.
4. Deleting your data
| App | Steps to delete | Wait time | Server-side retention after delete |
|---|---|---|---|
| Typical server-based budget apps | Email request, support ticket, or in-app form (varies) | Up to 30 days | 12–24 months for backups; longer where retention is legally required |
| Budget Lock | Settings → Destroy Vault → type "ERASE" | Instant | None — we have no servers |
5. Pricing
| App | Free tier | Paid tier |
|---|---|---|
| Budget Lock | Full features. Banner + interstitial + rewarded ads. | One-time "Remove Ads" IAP. No subscription, ever. |
| Typical server-based budget apps | Free with ads, or limited free tier | Subscription, typically $2.99–$15/mo or $35–$110/yr |
6. What we don’t do
Budget Lock has no bank linking, no automatic transaction import, no formal budgeting method with workshops or coaches, and no live "safe-to-spend" balance from connected accounts.
7. Which app should you use?
Choose Budget Lock if
- You want to track expenses without giving any company your email or transactions.
- You’re fine with manual or voice entry instead of bank-linked auto-import.
- You prefer a one-time purchase to a subscription.
- You want delete to be instant.
Choose another app if
- You need bank transactions to auto-import.
- You need a budgeting method with formal training.
- You need cross-device sync via a server.
