By registering for or using the Service, you agree to these Terms of Use. Any conflicting terms are hereby rejected.
JustALetter is an intentionally minimal messaging service: two connected people can send each other one message per day per connection. Each account can be connected to up to 2 other people (up to 3 with an active Premium subscription). This limitation is the core of the Service and remains in place; paid features only expand expression and the number of connections, not the daily message frequency per connection.
The free version of the Service may contain advertising in the form of flyers shown before you open a received letter; an active Premium subscription removes this advertising. Advertising content originates from advertising partners. The respective advertising partner is responsible for the content of linked external websites; we accept no liability for it. For details on data processing, see our Privacy Policy.
You must be at least 16 years old to use the Service. If you are younger, use is only permitted with the consent of a parent or legal guardian. You warrant that the information you provide upon registration is accurate.
An account is required to use the Service. You can sign in with email/password, Sign in with Google, or Sign in with Apple. You are responsible for keeping your credentials confidential and for all activity under your account. Please notify us immediately if you suspect unauthorized access.
To use the Service, you connect with other people via an invite code or shareable link, up to your account's connection limit (see Section 2). You may only send invitations to people you genuinely wish to connect with. You can end a connection at any time.
When a connection is ended, the shared letter history is archived and remains accessible to both people. Each person can individually hide the archived history from their app ("Delete history"). As long as only one person has hidden the history, the messages are retained, as they form part of the other person's correspondence. Only once both people have hidden the history are the associated messages and media permanently and irreversibly deleted, after a retention period of 2 years intended to preserve evidence in connection with unlawful content. For details, see our Privacy Policy.
You are solely responsible for the content you create (messages and any media). By design, your messages are transmitted to and visible by the person you are connected with. In particular, you must not send content that:
We do not actively monitor content, but we reserve the right to remove content and/or suspend accounts upon substantiated indications of violations.
You retain all rights to your content. You grant us only the simple, non-exclusive right necessary to provide the Service — namely to store, technically process, and transmit your content to the person you are connected with. We do not use your content beyond this.
The Service is free in its basic version. Optional paid features (e.g. extended messages, media, full history) may be offered in the future as a one-time purchase or subscription. In that case, purchase and billing are handled by the respective app store (Apple App Store or Google Play), whose terms additionally apply. Subscriptions renew as stated in the app store unless cancelled in time; management and cancellation take place via your app store account settings.
We strive for trouble-free operation but do not warrant any particular availability. Maintenance, technical faults, or force majeure may lead to temporary limitations. We reserve the right to further develop, change, or discontinue features insofar as this is reasonable for you.
You may delete your account at any time via the app settings, thereby ending the usage relationship. We may terminate the usage relationship for good cause — in particular for serious or repeated breaches of these Terms — with immediate effect, or suspend the affected account.
Upon account deletion, your user profile, authentication account, and any open invitations are deleted immediately. Active connections are automatically archived; the people you were connected with retain access to the shared letter history. Letters you have already sent remain with the recipient, as they form part of the recipient's own correspondence. A security record is retained for up to 2 years for content moderation purposes and to enable account restoration at your request. For details, see our Privacy Policy.
We are liable without limitation for damages arising from injury to life, body, or health, and for damages based on intent or gross negligence, as well as under the German Product Liability Act. For slightly negligent breaches of material contractual obligations (cardinal obligations), our liability is limited to the foreseeable damage typical for this type of contract. Otherwise, liability is excluded. For services provided free of charge, we are liable only for intent and gross negligence.
If you, as a consumer, enter into a paid contract (e.g. a subscription), you generally have a statutory 14-day right of withdrawal. For digital content, the right of withdrawal expires once performance has begun with your express consent before the end of the period and you have confirmed your acknowledgement of the loss of the right. Where a purchase is made through an app store, that store's refund terms additionally apply.
We reserve the right to adapt these Terms of Use where this is necessary for objective reasons (e.g. legal changes, new features). We will notify you of material changes in an appropriate manner. If you do not object within the notified period or continue to use the Service, the amended Terms are deemed accepted.
The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods; mandatory consumer-protection provisions of the country of your habitual residence remain unaffected.
The European Commission provides a platform for online dispute resolution (ODR): https://ec.europa.eu/consumers/odr. We are neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board.
Should any provision of these Terms be or become invalid, the validity of the remaining provisions shall remain unaffected. Statutory provisions shall apply by way of supplementary interpretation.
