Terms of Use

Version of 2026-10-22.

1. What zirkle is

Zirkle turns links to public videos into a short written summary, a Drop. The summaries are written by AI. They are a way into the source, not a replacement for it, and can contain mistakes. Check anything that matters at the source, which every Drop links to.

2. Your account

You must be at least 16. Keep your sign-in details to yourself. You can delete your account at any time under Account.

3. Your Drops

A Drop is private to you until you choose Publish. A published Drop can be read by anyone and appears in Explore; you can take it back at any time. You may publish only what you may publish. By publishing you allow us to show the Drop to others, free of charge, for as long as it is published. You cannot publish a Drop that includes your own documents.

4. Other people's content

Videos and articles belong to their creators and the platforms they are on. Zirkle is not affiliated with or endorsed by YouTube, TikTok, Instagram, X or any Creator. Zirkle uses YouTube API Services and, by using zirkle, you agree to be bound by the YouTube Terms of Service. We write summaries in our own words and link to the original. If you are a Creator and want your content left out, see For Creators.

5. What you must not do

Do not use zirkle to break the law or other people's rights, to harass or defame anyone, to publish unlawful content, to overload or attack the service, to get around its limits, or to collect Drops in bulk by automated means.

6. Reports and removal

You can report any Drop, and anyone can send us a notice at Report content. We look at every notice, tell the sender what we decided, and may unpublish or delete a Drop or stop summarizing a source. We may also do so on our own if a Drop breaks these Terms or the law.

7. Plans and limits

Zirkle has a free plan and a Pro plan with higher limits and extra features. Limits are shown in the app. If we start charging for Pro, the price, your right of withdrawal and how to cancel will be shown before you buy, and these Terms will say so.

8. Liability

We are fully liable for intent and gross negligence, for injury to life, body or health, and where mandatory law says so. For slight negligence we are liable only for breach of an essential contractual duty (one that makes the contract possible and that you can rely on), and then only for the typical, foreseeable damage. Summaries are produced by AI and offered without a guarantee that they are correct or complete.

9. Changes

We may change these Terms for good reason, for example a new feature or a change in the law. If a change matters to you we ask you to accept the new version before you make more Drops.

10. Law

German law applies, without taking away the mandatory consumer protection of the country where you live.
