Privacy Policy
AreaCalc GPS ("AreaCalc", "we", "us") is an app for measuring land area and distance on a map. This policy explains what information the app uses, where it goes, and the choices you have. It is provided by [legal name of the business or owner], [mailing address].
The short version
- You can use AreaCalc without an account. Without one, your measurements, projects and GPS recordings are saved only on your device.
- Your location is used only while the app is open, to show where you are and to trace a boundary as you walk it. We don't track your location in the background, and we don't receive your location unless you save a measurement to the cloud.
- If you create an account, your email address and the measurements and projects you save are stored in the cloud, so they back up and appear on your other devices.
- No ads, no analytics, no selling. We don't sell or rent your information, show ads, or use tracking or analytics tools.
- You can delete your account and its cloud data at any time, from inside the app.
Information on your device
Everything you create in AreaCalc is saved on your device first. That includes:
- measurement names and boundary points (latitude and longitude);
- cut-outs and the map view each measurement was saved with;
- projects (name, description, color);
- GPS recordings of boundaries you walk.
Without an account, this information never leaves your device. You can erase it by deleting the app.
AreaCalc also uses your device's time zone, only on the device, to choose a sensible starting map view. It isn't sent anywhere.
Location
AreaCalc asks for location permission when you tap the locate or record button. It uses your location only while the app is open:
- to show your position on the map;
- to trace a boundary while you walk it (GPS recording).
It never asks for background location. You can turn location access off at any time in your device's settings; drawing boundaries by hand still works.
Your location is not sent to us. A boundary you save contains the points of that boundary. If you have an account, those points are stored in the cloud, as described below.
Maps (Google)
The map is provided by Google Maps. To show map imagery, your device requests it from Google. Like any website or service, Google receives information such as your device's IP address and the area of the map being viewed. Where your location is shown on the map, Google's software on your device may also process it. Google handles this information under the Google Privacy Policy. We don't receive it.
Place search also uses Google. When you search for a place, what you type and the area of the map you're viewing are sent to Google (Places API) to suggest matching places, and the place you choose is looked up there to find its location. Typed coordinates aren't sent anywhere. Your recent searches are saved only on your device. We don't receive your searches.
Accounts and cloud backup
An account is optional. It is offered to AreaCalc GPS Pro subscribers for cloud backup and sync. If you create one, we store:
- Your email address and password. The password is stored only in hashed form; we can't see it. We use your email to sign you in, to send account codes (such as confirming your account or resetting your password), and to contact you about your account.
- The measurements and projects you save, including:
- boundary points, names and project details;
- when each was created and changed;
- the name or type of the device each change was made on (for example "iPad"), shown when the same measurement changes on two devices.
- Technical records needed to run the service, such as sign-in times and sync records. Our hosting provider may keep server logs, including IP addresses, for security and reliability.
GPS recordings are not uploaded; they stay on your device.
This information is stored with our hosting provider, Supabase, on servers in the United States. It is protected by encrypted connections, and access rules let each account read only its own data.
Purchases
AreaCalc GPS Pro is a subscription bought through the Apple App Store or Google Play. Apple or Google handles the payment. We never receive your card or payment details.
We use RevenueCat to check whether a subscription is active. RevenueCat receives:
- purchase information from Apple or Google (the product, purchase and renewal dates, and the transaction IDs);
- an app user ID. This is a random ID, or your AreaCalc account ID if you're signed in;
- basic device and app information (such as the app version and the device's country or region).
RevenueCat handles this under the RevenueCat Privacy Policy. We use it only to unlock Pro and, with an account, to turn on cloud backup.
How we use information
We use information only to:
- provide the app's features;
- keep your measurements backed up and in sync;
- sign you in;
- manage your subscription;
- respond to you when you contact us;
- keep the service secure.
We don't use it for advertising, and we don't sell it or share it with data brokers.
Who we share it with
We share information only with the providers that run parts of the service for us:
- Supabase: account and cloud hosting.
- RevenueCat: subscription status.
- Apple and Google: app stores and payments; maps.
- [Email provider, e.g. Resend]: sending account emails.
They may use it only to provide their service to us. We may also disclose information if the law requires it, or to protect the rights, property or safety of AreaCalc, our users or others.
How long we keep it
- On your device: information stays until you delete it or delete the app.
- In the cloud: information stays while you have an account.
- When you delete a measurement or project, it is removed from your devices. A deletion marker is kept so the deletion reaches your other devices.
- When you delete your account, your account and its cloud data are deleted right away.
- Copies in our provider's backups are overwritten within [N] days.
Deleting your account and data
To delete your account in the app: go to Account → Delete account. This deletes your account, your cloud measurements and projects, and your subscription record at RevenueCat. You can choose to keep or erase the copies on your device.
Deleting your account doesn't cancel a subscription. Cancel it in your App Store or Google Play account settings.
If you can't use the app, you can ask us to delete your account at privacy@areacalc.io or on our account deletion page.
Your rights and choices
You can view and change your measurements in the app at any time. Depending on where you live, you may have the right to:
- access, correct, delete or receive a copy of your personal information;
- object to or restrict how it is used;
- complain to your local data protection authority.
To make a request, email privacy@areacalc.io. We'll respond within the time the law allows (usually 30 days). We won't treat you differently for using these rights.
Children
AreaCalc isn't directed at children under 13, and we don't knowingly collect personal information from them. If you believe a child has created an account, contact us and we'll delete it.
International users
AreaCalc's cloud service is based in the United States. If you use cloud backup from outside the United States, your information is transferred to and stored in the United States, with the protections described in this policy.
Changes to this policy
If we change this policy, we'll update the effective date above. If a change significantly affects how your information is used, we'll also tell you in the app before it takes effect.
