Scalix Privacy Policy

Last updated: September 14, 2026

Scalix is a measurement, level, and unit/currency converter app for Android. This policy explains what data Scalix accesses and, just as importantly, what it does not do with it.

Data Scalix accesses on your device

• Camera — used only while you are actively using the AR ruler's camera-based measurement mode. Camera frames are processed on-device by Google's ARCore and are never recorded, stored, or transmitted anywhere.
• Motion sensors (accelerometer) — used to power the Level feature. Sensor readings are used live on-screen and are never stored or transmitted.

Data Scalix sends over the network

The only network requests Scalix makes on its own behalf are to Frankfurter (a free, open exchange-rate API) to fetch current currency conversion rates when you use the Currency tab. This request contains no personal information — it is a simple public rate lookup. Fetched rates are cached on your device so the converter keeps working offline; the cache contains only exchange rate numbers, nothing about you.

Advertising

Scalix shows a small banner ad, served by Google AdMob, to support free development. AdMob may collect your device's advertising ID and other device/app information to serve and measure ads, as described in Google's Partner Sites policy. This data is collected and processed by Google, not by Scalix directly. You can reset or opt out of personalized advertising in your device's Google Settings.

What Scalix does not do

• No account or sign-in of any kind.
• No analytics or tracking SDKs of its own, beyond the AdMob advertising SDK described above.
• No location access.
• No data is ever sold to third parties.
• No data leaves your device except the anonymous currency-rate lookup and the AdMob advertising traffic described above.

Data storage

Scalix stores your ruler calibration setting and cached currency rates locally on your device using Android's standard app storage. This data is deleted automatically if you uninstall the app.

Children's privacy

Scalix does not knowingly collect any information from anyone, including children, because it does not collect personal information at all.

Changes to this policy

If this policy changes, the update will be posted on this page with a revised date above.
