IQsolvo – Privacy Policy

Last updated: 22 October 2026

This policy covers the IQsolvo app (IQ test and logic puzzles), published on Google Play by Osli software. Earlier versions of the app were called Caliber.

We, the developer, do not collect, store on a server, or sell any personal information. Your puzzles, answers and scores stay on your device. The app shows ads from Google, and Google collects some data to show them; this is explained below.

What stays on your device

• Your tests and challenges: the puzzles you were given, the answers you chose, how long each one took, and your score range.
• Your puzzle rating and its history, your mistake notebook, your daily puzzle results and your practice.
• Your settings: theme, language, puzzle style and timed mode.

None of this is sent anywhere by the app. If backup is turned on for your phone, your phone may include this data in your own Google or Apple backup, as it does for other apps.

Ads

The app is free and shows one small banner ad above each puzzle, served by Google AdMob. The ads are not personalised: the app asks Google for ads that are not based on your interests or history.

To show ads, measure them and prevent fraud, Google receives information from your device, such as your advertising ID, IP address, device type and app version. Google, not the developer, handles this data under its own policy: How Google uses information from sites or apps that use its services. The developer never receives your advertising ID or any data that identifies you.

In the European Economic Area, the United Kingdom and Switzerland, the app asks for your choice first (Google's consent message), and you can choose Do not consent. You can change your choice at any time in the app: Settings → Ad privacy choices. You can also reset or delete your advertising ID in your phone's settings.

Purchases

If the app offers a one-time purchase, it is made through Google Play (or the App Store on iPhone). The store handles the payment; the app never sees your card or payment details.

Permissions (Android)

• Internet and network state: to load ads and to reach Google Play.
• Advertising ID and Android's ad services permissions: used by Google's ads code, as described above.
• Wake lock and foreground service: used by Google's ads code to finish its background work.
• Google Play billing: for purchases, if offered.

The app does not ask for your location, contacts, camera, microphone, photos or files.

Reporting a question

The flag at the top of a puzzle (and the link under each explanation) lets you report a problem with that puzzle. You choose what is wrong and can add details; nothing is sent until you tap Send. The report goes to the developer through Google Forms and contains only what you chose and wrote, the puzzle's code, and the app language and platform. It never includes your name, email or any ID. Google Forms is run by Google under Google's privacy policy.

Sharing

If you tap Share (a result card, a daily puzzle result or a challenge code), the app opens your phone's share menu and you choose where it goes. A challenge code only describes a set of puzzles; it contains nothing about you.

What the app does not do

• It has no account or sign-in, and never asks for your name or email address.
• It contains no analytics or tracking code of its own.
• It does not sell or share your data with anyone.

Children

The app is not directed at children under 13.

About the score

The app gives an unofficial IQ-style score from original puzzles, for practice and interest. It is not a clinical or official IQ assessment. Your score never leaves your device unless you share it.

Deleting your data

Uninstalling the app removes everything it saved on your device.

Changes

If this policy changes, this page will be updated before the change reaches the app.
