Privacy Policy

This policy covers simplegto.com, the range viewer at app.simplegto.com, and the Simple GTO app for iOS and Android.

What we collect

• Account & orders: your email address, purchase history, bundle entitlements, and subscription status.
• Payments: on the website, processed by Stripe. In the app, processed by Apple or Google. We never see or store your full card details. For website free trials, Stripe shares the card's brand, last four digits, country, and an anonymous card fingerprint with us, which we use only to stop the same card from starting repeated free trials.
• Sign-in and security: the IP address, browser or device type, and approximate country of each sign-in, kept to protect accounts and prevent abuse.
• Charts you open: when you are signed in, which charts you view, recorded on our own servers to run and improve the service.
• Email: if you opt in to our list, your email address and subscription status.
• Usage: if you allow analytics, the pages and screens you view, the actions you take, your approximate location from your IP address, and your browser or device type.

How we use it

• To deliver your purchases and provide download and chart access.
• To send receipts, sign-in codes, account emails, and, if you opted in, marketing.
• To keep accounts secure and prevent free-trial abuse.
• To understand aggregate sales and improve the product.

Cookies and analytics

Some cookies are essential: they keep you signed in and let checkout work. These are always on, because the site cannot function without them.

Everything else is analytics, which we run through PostHog to see how the site and the range viewer are used. This includes session recordings, which replay the pages you visited and where you clicked. Every form input is masked before it leaves your browser, so what you type, including your email address and payment details, is never recorded. We do not record the account or admin pages at all.

If you are in the EU, the EEA, the UK, or Switzerland, no analytics cookies are set and no recording starts unless you accept them. Everywhere else analytics is on by default and you can turn it off at any time using Cookie settings in the footer. We also record when a subscription starts, on our own servers, so we can count sales accurately. That happens regardless of your cookie choice, because it is a record of your purchase rather than tracking.

In the app

You sign in to the app with your email address and a one-time code we email you. Your account is the same one you use on the website.

Subscriptions bought in the app are billed by Apple or Google. RevenueCat processes them for us, and we receive your subscription's product, status, and renewal dates, linked to your account. We never receive your payment details.

The app uses PostHog analytics, linked to your account ID, to see which charts people open and where the app gets stuck. It never records your screen. If you are in the EU, the EEA, the UK, or Switzerland, or we cannot tell where you are, analytics stays off unless you allow it. Everywhere else it is on by default. You can turn it off at any time under Privacy in the app's menu. The app does not show ads and does not track you across other companies' apps or websites.

If the app crashes, it sends a crash report to Sentry so we can fix the problem. A crash report carries the app version, your device model and operating system, and the error itself. It never includes your email or your account details.

Sharing

We share data only with the processors that run the service (Stripe, Apple and Google for in-app purchases, RevenueCat for app subscriptions, Resend for email, PostHog for analytics, Sentry for app crash reports, and our hosting/storage providers). We do not sell your data.

Your choices

You can change your analytics choice at any time using Cookie settings in the footer, or under Privacy in the app. You can unsubscribe from marketing email via the link in any message. You can delete your account and its data yourself at any time from simplegto.com/account/delete or in the app (Account, then Delete account). Deleting your account does not cancel an App Store or Google Play subscription; cancel that in your store settings. Order and payment records we must keep for tax purposes, and any feedback you sent us, are kept without your name or email. To request a copy of your data, or for anything else, email admin@simplegto.com.
