1. Side-by-Side Comparison: How Budget Lock Compares to Other Apps
| App | Account required | Data sent to a server | Bank linking | Pricing |
|---|---|---|---|---|
| Budget Lock | No | None (your transactions never leave your phone) | No | Free + one-time Remove Ads IAP ($4.99) • 0 personal data points collected |
| Typical cloud budget apps (e.g., YNAB, Monarch, Copilot) | Yes (account required) | Yes — synced to the provider’s servers | Yes — bank linking is a core feature | Subscription pricing — check each app for current rates |
Most cloud budget apps require an account and store your data on their servers. Budget Lock requires no account and publishes its full encryption algorithm stack — see Security.
2. Privacy & Data Collection: What Personal Information is Tracked?
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. On-Device Encryption: How is Financial Data Secured?
| App | Encryption claim |
|---|---|
| Typical cloud budget apps (e.g., YNAB, Monarch, Copilot) | Details vary by provider; most cloud apps encrypt data in transit (TLS) and store it on their own servers, where it can be decrypted. Check each app’s security page for specifics. |
| Budget Lock | AES-256 (NIST FIPS 197) on-device, with key derivation via PBKDF2 (NIST SP 800-132) stretched 100,000 times. |
See the Security page for the full details.
4. Deleting Your Data: How Long Does the Deletion Process Take?
| App | Steps to delete | Wait time | Server-side retention after delete |
|---|---|---|---|
| Typical cloud budget apps (e.g., YNAB, Monarch, Copilot) | Email request, support ticket, or in-app button. | Varies by provider (often up to 30 days). | Varies by provider — see each app’s privacy policy and data-retention terms. |
| Budget Lock | Settings → Destroy Vault → type "ERASE" | Instant | None — we have no servers |
5. Cost Comparison: What is the Pricing Model of Budget Lock?
| App | Free tier | Paid tier |
|---|---|---|
| Budget Lock | Full features. Banner + interstitial + rewarded ads. | One-time "Remove Ads" purchase ($4.99). No subscription, ever. |
