Terms of Use

Flow is operated from Germany. For all legal texts (imprint, privacy policy and terms of use), only the German version is legally binding. This English version is a translation for your convenience only; in the event of any discrepancy, the German version shall prevail.

Version of 4 November 2026

§ 1 Scope and provider

These terms of use apply to the use of the web app “Flow” (hereinafter “Flow” or the “service”). The provider is Nicolas Matschke (for contact details see the legal notice). By registering, you agree to these terms.

§ 2 Services

Flow is a tool for focused work with a timer, tasks, statistics and playful rewards. Using it is free of charge. There is no entitlement to any particular availability, to particular features or to Flow being operated permanently.

§ 3 Account

  1. You need an account to use Flow. You must be at least 16 years old; younger people need the consent of their parents or guardians.
  2. Your details must be accurate. Keep your password secret and let us know if you suspect that your account is being misused.
  3. Each username exists only once. It may be visible to others (leaderboard, events) and must not infringe the rights of third parties or be offensive, discriminatory, harmful to minors or otherwise unlawful.
  4. There is no entitlement to the creation or continued existence of an account.

§ 4 Virtual items and records

  1. XP, levels, “records” and all items in the record shop (e.g. clothing, decor, rooms, record crates) are purely virtual game content. They can only be earned by using Flow and cannot be bought with real money.
  2. Virtual content has no monetary value and cannot be paid out, sold or transferred to other accounts. You merely acquire a simple, non-transferable right to use it within Flow, which ends when your account is deleted.
  3. Record crates contain a randomly selected item; the probabilities are shown before opening.

§ 5 Fair use

In particular, it is not permitted to:

  • influence rewards, leaderboards or events through automation, scripts, manipulating the clock or exploiting bugs,
  • create multiple accounts to gain advantages on leaderboards or in events,
  • endanger the security of Flow, circumvent protective measures or put excessive load on the service,
  • use Flow for unlawful purposes.

Please report any security vulnerabilities you find confidentially to the contact address in the legal notice.

§ 6 Your content

Notes, intentions, tasks and thoughts that you create in Flow belong to you. You only grant us the rights necessary to store and display them for you. This content is stored encrypted and is not published. You are responsible for not storing any unlawful content. Also back up important content via the data export.

§ 7 Rights of the provider

To keep Flow fair, secure and affordable, we may:

  1. Develop Flow further: change, add or remove features as far as this is reasonable for you, and temporarily switch Flow off for maintenance and updates.
  2. Adjust virtual content: change prices, rewards, probabilities and the range of items in the record shop, end or reset events and leaderboards, and correct content that was awarded in error.
  3. Take action against violations: remove rewards, items or placements obtained through manipulation, exclude people from leaderboards and events, change inappropriate usernames and temporarily lock accounts.
  4. Delete accounts, as described in § 9.

We exercise these rights at our reasonable discretion, taking your legitimate interests into account.

§ 8 Health

Flow is not a medical device and does not replace medical or therapeutic advice. Break exercises, timer recommendations and tips are general suggestions. Only do exercises if you feel well doing them, and stop if you experience any discomfort.

§ 9 Term, termination and deletion

  1. The user agreement runs for an indefinite period.
  2. You can end it at any time without notice by deleting your account in the settings. All data is then deleted immediately and cannot be restored.
  3. We may terminate the user agreement at any time without giving reasons with 14 days’ notice and then delete your account. We announce this in the app and (if an address is on file) by email, and remind you once more 3 days before the deletion. Until the deletion you can continue to use Flow and export your data.
  4. For good cause we may lock or delete your account without notice, in particular in the event of serious or repeated violations of these terms, a threat to the security of Flow or of other users, or if we are legally obliged to do so. Where reasonable, we will lock the account first and give you the opportunity to respond.
  5. Inactive accounts: We automatically delete accounts that have not been used for 12 months. We remind you by email 30 days and again 3 days beforehand if an address is on file. If a reminder cannot be delivered, we do not delete the account. Signing in once is enough to keep the account.
  6. We may discontinue Flow as a whole with 14 days’ notice. We will inform you in good time so that you can export your data.
  7. When an account is deleted, all virtual content expires without replacement. There is no entitlement to restoration, transfer or compensation.

§ 10 Liability

  1. We are liable without limitation for intent and gross negligence, for injury to life, body or health and under the German Product Liability Act.
  2. As Flow is offered free of charge, we are otherwise not liable for slight negligence.
  3. We back up data according to the state of the art, but cannot guarantee that data will never be lost. Also use the data export for important content.

§ 11 Changes to these terms

We may change these terms of use if Flow, the legal situation or case law changes. We will inform you about changes in the app. Material changes only apply once you agree to them; if you do not agree, you can delete your account at any time. If you do not give your consent, we may terminate the user agreement in accordance with § 9(3).

§ 12 Final provisions

  1. The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer habitually resident in the EU, mandatory consumer protection provisions of your country of residence remain unaffected.
  2. Should individual provisions be invalid, the remainder of the agreement remains valid; the invalid provision is replaced by the statutory provisions (§ 306 BGB).
  3. Flow is operated from Germany; the contract language is German. Only the German version of these terms of use is legally binding. This English version is a translation for your convenience only. In the event of any discrepancy, the German version shall prevail.
Flow: focused work while the rain falls outside.
