Privacy policy

Last updated: 12 November 2026

Reminder Companion is a water reminder for Windows. It runs on your own PC. This page explains what it keeps, and the little it sends over the internet.

What stays on your PC

Your settings, your water history and any companions you add yourself are kept in a folder on your PC (%APPDATA%\Reminder Companion). They are never sent anywhere. There is no account, and the app has no analytics, advertising or tracking.

What it sends over the internet

Withdrawn licence keys: the paid edition downloads the public list of withdrawn keys from our small update server (hosted by Cloudflare) at start-up, when Settings opens, and at most hourly. That request sends nothing about you.
Updates (licensed copies): a few times a day the app asks the same server for a newer version. So that only buyers get updates, that request shows your licence key, which holds the name you gave when you bought it and your PC's code, not your PC's identity. The server doesn't store it. Updates install when the app quits, or when you choose Restart now.

Like any website, the server's host may keep short-lived technical logs such as your internet address.

Buying a licence

The paid edition shows a short PC code (for example 8G0B-SZFG), made from a one-way scramble of your PC's ID, so the ID itself can't be worked out from it. We keep the details below only to make your licence key, to help you with it later, and to withdraw a key that was shared or refunded. They're used for nothing else, and never shared or sold. To have them removed, email us.

On the payment page: payments are handled by Razorpay. Your card, UPI or bank details go to Razorpay, under Razorpay's own privacy policy; we never see them. The page asks for your name, email, phone number and PC code. Razorpay passes those, with the amount, how you paid and the payment's reference, to our small order server (run on Cloudflare), so we can make your key.
Paying by UPI directly: you send us your PC code with your name, your contact (WhatsApp or email) and your payment reference. The payment goes through your own UPI app.

Children

Reminder Companion isn't aimed at children under 13 and doesn't knowingly collect anything from them.
