Terms of use
Last updated October 29, 2026
These terms cover the myMRR iOS app, made by Castedev ("we"). By using myMRR you agree to them, along with Apple's Licensed Application End User License Agreement. Where the two differ, these terms apply.
What myMRR does
myMRR reads your revenue from Stripe, RevenueCat and Polar using API keys you create, and shows it on your iPhone. It has no server: everything happens on your device. Our privacy policy explains what that means for your data.
Your keys and accounts
- You are responsible for the keys you create and add. Use read-only keys, as the app asks; you can revoke them at any time from each provider's dashboard.
- Your use of Stripe, RevenueCat and Polar is governed by their own terms. myMRR is not made by, endorsed by or affiliated with any of them.
The numbers
myMRR computes its figures from what each provider's API returns, and converts currencies with the European Central Bank's daily reference rates. They can differ from a provider's own dashboard, for example in how fees, refunds, trials or currency conversion are counted. Treat them as a guide. They are not financial, tax or accounting advice; check your provider's records before relying on a figure.
The free version and the unlock
- myMRR is free to download. "Unlock myMRR" is a one-time, non-consumable in-app purchase, with no subscription.
- Apple processes the payment. Refunds are handled by Apple under its policies: you can ask for one at reportaproblem.apple.com.
- The unlock stays with your Apple Account. Use Restore purchase in the app on a new device or after reinstalling.
Acceptable use
Only add keys for accounts you own or are allowed to access. Don't try to reverse engineer, resell or misuse the app.
Changes and availability
We work to keep myMRR accurate and working, but it depends on third-party APIs that can change or go down. We may update, change or remove features. If a provider changes its API, a source may stop working until an update fixes it.
Warranty and liability
myMRR is provided "as is", without warranties of any kind beyond those the law requires. To the extent the law allows, we are not liable for indirect or consequential losses, or for decisions made based on the figures the app shows. Our total liability is limited to the amount you paid for the app. Nothing in these terms limits rights you have as a consumer that cannot be limited by contract.
Changes to these terms
If these terms change, we'll update them here and change the date at the top. Using myMRR after a change means you accept the new terms.
