Your data stays local.
We build single-purpose Android utilities that compute everything on your own hardware. No remote databases, no tracking pixels, and absolutely zero external servers.
Three rules of local utility.
Local storage only
Zero tracking SDKs
One-time upgrades
Our Android packages contain zero analytics SDKs, zero advertising trackers, and zero telemetry. We measure app success purely by Google Play store reviews.
We monetize through simple, one-time pro upgrades that unlock advanced utility. No recurring subscriptions, no paywalls on basic math, and no data broker partnerships.
Every dividend transaction, compound calculation, and interest projection is saved directly to your device's secure SQLite database. We cannot read it.
Clear answers on security.
How do updates work offline?
Why build Android-first?
Our calculations rely on manual input or local configuration files. When stock data or dividend yields change, you update them in three taps without syncing to external databases.
Android provides robust sandboxing and local storage controls. By focusing entirely on native Kotlin code, we maximize performance and respect your device's system-level privacy permissions.
Is my data backed up?
Are the apps open source?
Because we do not run servers, we do not perform cloud backups. You can export your data to a standard JSON file directly to your local Android storage.
We are transitioning our core calculation engines to public repositories. You can audit our mathematical formulas and verify our zero-network-activity claims directly on GitHub.
