Terms of Service

1. Provider and scope

These Terms govern use of the Don't Break Two mobile application and its paid and server-backed services. The provider is Tim Gabel, trading as HowtoHabit. Contact details are stated in the Impressum.

2. Purpose of the app

Don't Break Two is a habit-tracking and self-management tool focused on consistency, recovery after missed opportunities and gradual habit development. It does not provide medical, psychological, legal, financial or other professional advice.

3. Accounts and access

A Don't Break Two account is required to use the app. Authentication is used to establish the user identity needed for account access, legal-version tracking, account deletion, entitlement handling and server-backed features. Core habit data remains local-first: signing in does not by itself upload, replace or erase locally stored habit data.

4. Premium subscriptions and billing

Don't Break Two Premium is offered through auto-renewing subscription options such as Monthly and Yearly. Both current subscription options provide the same Premium entitlement, including AI Coach; only billing cadence and store-managed subscription expiry differ. The exact price, billing period, renewal terms and product description shown by the applicable app store at the time of purchase are authoritative.

Payment processing, renewal, cancellation and store refunds are handled by the applicable app store under its terms. Purchases require secure server-side verification before Premium is enabled. Historical internal/test Lifetime entitlements may be honored for compatibility but are not a current public purchase option.

5. Auto-renewal and cancellation

Premium subscriptions renew according to the billing period displayed by the store unless cancelled through the user's store account within the store's applicable cancellation rules. Removing the app or deleting a Don't Break Two account does not itself cancel a store subscription. A cancelled subscription may remain active until the end of the already-paid period.

6. AI Coach

AI Coach is included with an active current Premium subscription. It is an AI system that interacts directly with the user: responses are generated by an external AI model through the Don't Break Two backend, not by a human coach. The app identifies the feature as AI-generated guidance at or before the user's first interaction. Relevant habit context and analytics may be transmitted to generate a response as described in the Privacy Policy. AI output may be incomplete, inaccurate or unsuitable for a particular situation. Coach must not be used for emergencies, diagnosis, treatment decisions or other high-stakes professional decisions.

7. Trajectory evaluation and machine learning

Premium may evaluate whether a habit appears to be building, stabilising, recovering, eroding, overreaching or otherwise changing direction. These trajectory labels are decision-support signals based on recorded behavior and product heuristics; they are not guarantees, diagnoses or scientifically calibrated probabilities of future behavior.

Don't Break Two may improve a shared trajectory model using bounded numerical learning signals derived on the device from past execution patterns. No habit names, target text, free text, account identifier, habit identifier, exact event history or per-user training history is retained in the machine-learning model. Accepted learning samples update shared aggregate model parameters and are then discarded.

8. User responsibility

You are responsible for information you enter and for deciding whether a habit, schedule or suggested action is appropriate for you. Do not submit unlawful material, third-party confidential information you are not permitted to process, or content that infringes the rights of others.

9. Availability, updates and changes

The app and individual features may be corrected, improved, changed, temporarily unavailable or discontinued where reasonably necessary for security, legal, operational or product reasons. Habit data is designed to remain local-first after authentication, but access to the app requires an authenticated account and may therefore depend on authentication services being available.

10. Accounts and termination

You may stop using the app at any time. You may sign out or delete your server account through the app where available. Signing out returns the app to the authentication screen. Account deletion removes the server account and, after server deletion succeeds, deletes that account's local Don't Break Two data from this device. It does not cancel a store subscription. If you later want to use the app again, a valid account is required. Other local app data can also be removed by deleting app data or uninstalling the app, subject to platform behavior.

11. Liability

Mandatory statutory liability remains unaffected, including liability for intent, gross negligence, injury to life, body or health and liability under mandatory product-liability law. Where liability for ordinary negligence may lawfully be limited, liability is limited to foreseeable damage resulting from breach of essential contractual obligations.

12. Consumer rights

Nothing in these Terms limits mandatory consumer-protection rights. Statutory rights and any rights provided directly by the applicable app store remain unaffected.

13. Applicable law

German law applies where legally permissible. Mandatory consumer-protection provisions of the country in which a consumer has their habitual residence remain unaffected.
