CoolCalc is a fully on-device HVAC load calculation tool. We do not collect, use, or share any of your personal data.
Below is a summary of each data category and how you control it.
Rooms, scan records, and calculation results you create.
Where it's stored: Local UserDefaults only.
Your control: Delete individual projects in the app, or remove the app to erase everything.
Approximate city-level location used for climate data lookup.
Your control:
You can still enter a city name manually when location is off.
Room geometry captured via Apple's RoomPlan API.
Where it's processed: On-device only.
Your control:
You can still enter room dimensions manually when camera is off.
This app contains no analytics SDK, advertising SDK, or third-party tracking code.
Your control: Nothing to do.
To delete all data: remove individual projects in the app, or delete the app from your home screen (iOS removes UserDefaults data when an app is deleted).
Since no data ever leaves your device, there is no server-side breach risk. If a future version adds network features, we will update this policy and re-prompt for consent within the app.
