Terms of use for the Postklar beta

1. Provider and scope

1.1 Postklar is provided by ARCH VISION UG (haftungsbeschränkt), Unterbiberger Straße 20, 81737 Munich, represented by managing director Maryam Rabiee, Amtsgericht München HRB 316080, email: info@postklar.de ("we").

1.2 These terms apply to the beta version of the Postklar app (iOS, Android) and web app (app.postklar.de) ("beta").

1.3 Users' own terms do not apply.

2. What the beta is

2.1 Postklar is a digital archive for letters. Users can photograph, upload, share from other apps or forward letters by email to a personal address. An AI reads them, summarises them, picks out deadlines, amounts and senders, and answers questions about the user's own archive.

2.2 The beta is a test version. It may contain errors, be incomplete and change at any time. Features may be added, changed or removed; some are enabled only for selected test accounts.

2.3 The beta is free of charge. Usage limits apply and are shown in the app (currently on the free plan: 5 letters per month, at most 3 per day); we may adjust them during the beta. No payment obligation arises. If paid plans are introduced, this happens only after separate notice and only if you expressly take out such a plan.

3. Participation and account

3.1 Participants must be at least 18 years old.

3.2 An account with a valid email address is required. Keep your access and device protected; we recommend the app lock.

3.3 There is no right to take part in the beta.

4. Your content

4.1 You only upload letters and documents you own or are entitled to manage (e.g. post addressed to you, your children or a person in your care). You keep all rights in your content.

4.2 You grant us the rights needed to store, encrypt, have the AI read, display and – at your request – share your content for you. We do not use your content for advertising or to train AI models.

4.3 When you share letters (link, family, company space) you decide who gets access. In a family, the family admin can read members' archives after the member has confirmed this; health letters and sensitive letters stay hidden until the member allows them. Letters you upload to a company space are assigned to that space; the company has control of them. They stay there after your account is deleted.

4.4 In particular it is forbidden to upload content whose possession or processing is unlawful, to overload Postklar, to circumvent security measures, or to scrape the service automatically.

5. AI output: descriptive only, no advice

5.1 Summaries, detected deadlines, amounts, categories, translations and Ask answers are generated automatically by an AI. They describe what your letters say. They are not legal, tax, financial or medical advice and not a recommendation to do or not do anything.

5.2 AI output may be wrong or incomplete – e.g. with poor image quality, handwriting or unusual forms. The original letter always prevails. Check deadlines, amounts and payment details against the original before acting.

5.3 Deadline reminders are an aid. We do not promise that every deadline is detected or that every reminder arrives on time. Meeting deadlines remains your responsibility.

5.4 For legal, tax or health questions, contact a qualified professional (lawyer, tax adviser, doctor, advice centre).

6. Keep your originals

6.1 Postklar does not replace keeping your originals. Keep original letters and documents, especially where the law requires it or the original may be needed as evidence.

6.2 Data loss can happen, especially in a beta. Use the export if you want your own copy of your archive.

7. Availability

We try to run the service without disruption but owe no particular availability during the beta. Maintenance, development, provider outages or security reasons may cause interruptions.

8. Feedback

We welcome feedback (e.g. to info@postklar.de). You may give suggestions freely; we may use them free of charge to improve Postklar. Please do not send letter contents or sensitive data with feedback unless needed.

9. Liability

9.1 We are liable without limitation for intent and gross negligence, for injury to life, body or health, under the Product Liability Act, and to the extent of any guarantee given.

9.2 For slightly negligent breach of an essential contractual obligation (one whose fulfilment makes proper performance of the contract possible at all and on which you may regularly rely), our liability is limited to the foreseeable damage typical for the contract; liability for slight negligence is otherwise excluded.

9.3 For damage resulting from AI output (section 5) being relied on unchecked or originals not being kept (section 6), we are liable within 9.1 and 9.2; contributory fault is taken into account.

9.4 For loss of data we are liable only to the extent it would not have occurred with regular own backups (e.g. via export).

9.5 These rules also apply in favour of our staff and agents.

10. Term, termination, deletion

10.1 You can stop using Postklar at any time and delete your account in the app. Your data is then deleted as described in the privacy policy; letters you uploaded into a company space stay with the company.

10.2 We can end your beta participation with 14 days' notice by email, and without notice for good cause (e.g. breach of 4.4).

10.3 We can end the beta as a whole. We announce this at least 30 days in advance and give you the chance to export your data. On transition to regular operation your data is kept unless you choose otherwise; paid plans then have separate terms.

11. Changes to these terms

We may change these terms during the beta with effect for the future, e.g. when features or the law change. We tell you about changes in the app at least 14 days in advance. They apply only once you accept them in the app; until then you can keep using the beta under the previous terms or stop using it.

12. Data protection

How we process personal data is explained in our privacy policy for the app.

13. Final provisions

13.1 German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers this choice of law applies only insofar as it does not remove the protection of mandatory provisions of the country of their habitual residence.

13.2 If the user is a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction is Munich.

13.3 We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board.

13.4 If a provision is invalid, the rest of the contract remains valid; the statutory provisions apply instead.
