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	No financial records. Your transactions stay on the phone unless you dictate one or turn on cloud backup.	No	Free + one-time Remove Ads purchase • no account, no bank linking
Typical cloud budget apps	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 cloud budget apps collect

Typically an email address and password, device and usage identifiers, and — where bank linking is offered — balances and transactions from the accounts you connect. What each app collects is set out in its own privacy policy; read those rather than taking a summary at face value.

Budget Lock collects

No account, so no email or password. No bank linking, so no balances or transactions. No SMS, no contacts, no location. On the free tier AdMob sees an advertising ID and basic device information — the one-time Remove Ads purchase switches it off. Your financial records stay on your phone either way.

Typical cloud budget apps	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.
