I'm an individual developer, and I wanted you to enjoy my app without complicated data policies. I follow the strict rules of Europe’s GDPR and ePrivacy laws.
In short: I don't personally collect, store, or sell any of your names, emails, or personal information.
The only personal data processing that happens in this app is through Google Admob, which displays ads so I can keep the app free for you.
However, the purchase token and App ID will be used for fraud check when you submit a purchase restore request in the app settings.
Since my app shows ads using Google AdMob, their system automatically collects certain technical identifiers from your device to make the ads work. This data is processed by Google and its network of partners.
| What Is Collected | Why It's Collected |
|---|---|
| Device Identifiers (AAID/IDFA) | To limit how often you see the same ad, prevent fraud, and measure ad performance. |
| IP Address | To guess your general location (e.g., country/region) so you get locally relevant ads and to comply with regional laws. |
| App Usage Data | To record when you see and click on an ad, which helps advertisers pay me. |
| Technical Data | To ensure the ads load correctly on your device and operating system. |
Because AdMob uses your device's identifiers for personalized ads, I must get your explicit permission first, as required by law (ePrivacy/GDPR).
You have the right to change or withdraw your consent at any time.
To change your settings, go to: Classic Calculator > Settings > Privacy
Your device data is shared with Google Admob and its Ad Technology Providers (ATPs). These transfers may occur outside of Europe (e.g., to the USA).
Google uses legal safeguards (like Standard Contractual Clauses) to ensure the data is protected under GDPR standards.

As an EU/UK user, you have the right to access, correct, or delete the data associated with this app. Since I only process data through AdMob, exercising these rights involves managing your advertising settings or contacting me for a data request.
If you have any questions or wish to exercise your rights, please contact me directly:
Email: [email protected]
If you feel I have not handled your request properly, you can file a complaint with your local Data Protection Authority (Supervisory Authority) in the EU/UK.
This app is directed at a general audience, but I do not knowingly collect personal data from children under the age of 16. If you are a parent and believe your child has provided me with data without your consent, please contact me.
