Apps that keep your data on your phone.

I'm an indie developer of Android apps that combine privacy and simplicity. They work without an account and without the Internet permission: what you enter stays with you, and I never see it.

The apps

Two apps, one promise.

Free Android apps, designed with privacy and simplicity in mind.

MemoLock

Encrypted, private notes

A private notepad whose memos, photos and voice notes are encrypted on your phone. Unlock with a code or your fingerprint; the app has no Internet permission.

  • AES-256 encryption
  • Code or fingerprint
  • Encrypted backup
  • No Internet access

Version 2.1.0 · Free · Android

Staticar

Car logbook & real costs

Fuel consumption, cost per kilometre, expenses and service log, with reminders before the roadworthiness test or the insurance renewal. 100% local, no account, no ads.

  • Fuel consumption
  • Cost per km
  • Smart reminders
  • No Internet access

Version 1.4.1 · Free · Android

Privacy first

What you enter stays yours.

Not a setting, not a promise in small print: it is how the apps are built.

Stays on your phone

No account, no cloud sync, no server. What you enter never leaves the device unless you export it yourself.

No Internet permission

Neither app can go online: Android simply doesn't let them. They work completely offline.

Nothing collected

No analytics, no crash reporting, no advertising SDK. I never see your data.

No hidden copies

MemoLock stays out of Google backup and offers its own encrypted backup file instead.

Coming to Google Play

Play it first: become a tester.

Some apps are still in closed testing on Google Play. Join the test, play before everyone else and help them get released.

Superalloy

3D tower defense game

A colourful, punchy 3D tower defense where every level is won by reading the map: which monsters are coming, which way, and what they shrug off. Build towers, send heroes onto the road and cast spells at the right moment.

A game, made differently from the two apps above: it shows optional rewarded ads and has its own privacy policy.

Superalloy battle in the forest: towers on their pedestals, monsters on the road
