Security and privacy built on verifiable facts.
We do not make empty marketing promises or claim impossible guarantees. We implement strict technical controls and deliberately avoid collecting what we do not need.
How your family data is protected
Standardized, verifiable cryptographic protocols and access barriers.
TLS 1.3 in Transit
All communication between your Android device and Kestro cloud servers is encrypted using modern TLS 1.3 transport security.
AES-256 Storage Encryption
Database records and backups are encrypted at rest using AES-256 algorithms. Household data is separated by strict tenancy checks.
Deliberate Logging (Zero SMS Scraping)
We believe privacy begins with not collecting unnecessary data. Expenses are logged intentionally, preventing inadvertent personal data leakage.
Biometric & PIN Device Lock
Lock Kestro locally on your device using your fingerprint or screen PIN. Even if a relative or friend borrows your phone, your ledger remains secure.
What Kestro will never ask for or touch
True privacy is about knowing what software cannot do.
Netbanking Passwords & PINs
Kestro never asks for, records, or stores your internet banking logins, ATM PINs, or UPI security codes.
Bank Account Credentials
We do not connect directly to your bank accounts with screen scrapers or store your bank credentials.
SMS Inbox Reading
Kestro does not request permission to read your personal text messages, OTPs, or private chat histories.
Credit Card Numbers & CVVs
All subscription billing is handled exclusively through Google Play Store billing. We never see or store card numbers.
