Terms of use

Plain terms for the apps, watch faces and this website.

Last updated 1 March 2026 · Algorion OÜ, Tallinn, Estonia

1. Who you are dealing with

The products described on this site are published by Algorion OÜ, trading as Hetko, registered in Estonia. Using them means accepting these terms. Where an app store's own terms conflict with ours, theirs govern the purchase itself.

2. Your licence

You get a personal, non-exclusive licence to install and use our products on devices you control, for as long as you comply with these terms. You may not resell them, redistribute the binaries, decompile them except where law permits, or strip out our branding to publish them as your own.

3. Purchases, trials and refunds

All payments run through Google Play, the App Store or Steam. They hold the billing relationship, so refunds follow their policy and their window. Beyond that window we will still approve a refund where a product genuinely does not work on your device - write to us.

Where a subscription exists, it renews until you cancel it in the store account that bought it. We cannot cancel it for you.

4. Your content

Books you import, notes you write and saves you keep are yours. We claim no rights over them, and in most cases we never see them. You are responsible for having the right to the files you open in our apps.

5. Third-party services

Some products connect to services we do not run: OPDS catalogues, app store billing, Wear OS complication providers. Their availability, pricing and rules are theirs, not ours.

6. Acceptable use

Do not use our products to break the law, to circumvent another service's access controls, or to interfere with our infrastructure or other users. We may withdraw a licence that is being used this way.

7. Warranty and liability

Our products are provided as they are. We do not promise uninterrupted streaming, perfect rendering of every file, or compatibility with every device. Nothing here limits the statutory rights you have as a consumer in the EU, and nothing excludes liability for intent or gross negligence. Otherwise our liability is limited to what you paid us in the twelve months before the claim.

8. Changes and ending

We may update these terms; material changes get a new date here and a note in release notes. You can end the agreement any time by uninstalling. We may end it if you breach these terms.

9. Law and disputes

Estonian law applies, with the courts of Tallinn competent, without removing the right of a consumer to bring a claim where they live. Before any of that, mail hi@hetko.eu - most things get sorted that way.
