Terms of use

Last updated: 6 October 2026

These terms of use govern the use of the FastDoc QES app for iOS and Android. The provider is BrainWave Software GmbH, Heilig-Kreuz-Straße 24, 86152 Augsburg, Germany ("we").

1. Scope

1.1 These terms apply to all use of the app. The terms of the app store you obtain the app from also apply (Apple Media Services Terms / Licensed Application End User License Agreement, or the Google Play Terms of Service).

1.2 The app is intended for health professionals who hold an electronic health professional card (eHBA), and for their organisations.

2. What the app does

2.1 The app lets you create qualified electronic signatures (QES) on PDF documents in PAdES format using your eHBA via NFC. Before every signature the app checks the validity of your certificate with your card's issuer (OCSP) and embeds the result in the signature.

2.2 The signature is created by your card using the qualified certificate issued to you by your trust service provider. We are not a trust service provider and do not issue certificates.

2.3 Documents are processed exclusively on your device. We do not store documents and can neither view nor recover them.

2.4 Features marked "coming soon" (e.g. batch signing, practice connection) are announced but not yet part of the service. You are entitled to them only once they are released in the app.

3. Requirements

You need an eHBA of generation G2.1 with NFC and an active PIN.QES (or the transport PIN for first-time setup), a smartphone with NFC running a supported operating system version, and an internet connection for the certificate check. NFC behaviour varies between devices. Please test the app with the free trial signatures before buying a subscription.

4. Trial, subscription and payment

4.1 You can create two signatures free of charge. After that, a paid subscription with a term of one or two years is required. The prices shown in the store before purchase apply.

4.2 Purchase, payment, term, renewal, cancellation and refunds are governed by Apple's or Google's terms. The store shows you before purchase whether and how a subscription renews. You can cancel in your store's subscription settings. Any statutory right of withdrawal is exercised with the respective store.

4.3 Your subscription is tied to your Apple ID or Google account and can be restored after reinstalling the app.

5. Licence

For the duration of use we grant you a simple, non-transferable right to use the app on your devices in accordance with these terms and the store terms. You may not modify, decompile or reverse engineer the app except as permitted by Section 69e of the German Copyright Act (UrhG) or other mandatory law.

6. Your obligations

• Keep your PIN.QES secret and enter it only in the app, never in emails or to our support team.
• Check every document before signing. You sign the content the app shows you.
• Keep your eHBA safe and have it blocked by your card issuer immediately if it is lost or misuse is suspected.
• When choosing where to store signed documents and whom to share them with, observe your professional obligations, in particular medical confidentiality and data protection law.
• Back up your documents yourself. The app does not create backups.

7. Legal effect of the signature

Under Art. 25(2) of the eIDAS Regulation, a qualified electronic signature has the same legal effect as a handwritten signature. It is your responsibility to determine whether a QES is sufficient for a particular document or whether another form is required. Information on our website and in the app is general information, not legal advice.

8. Availability and changes to the app

The certificate check depends on services of your card issuer that are outside our control. If such a service is unreachable, signing may be temporarily unavailable. We continue to develop the app and adapt it to new operating system versions, card generations and legal requirements. We will not restrict essential features of an active subscription in doing so.

9. Liability

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

9.2 For slightly negligent breach of an essential contractual obligation (an obligation whose fulfilment makes proper performance of the contract possible in the first place and on whose fulfilment you may regularly rely), our liability is limited to the foreseeable damage typical for this type of contract. Otherwise, liability for slight negligence is excluded.

9.3 For loss of data we are only liable for the effort that would have been required to restore it had you backed up your data regularly.

10. Changes to these terms

We may change these terms with effect for the future where there is a valid reason (e.g. new features or changes in the law). We will inform you of material changes in the app in good time. For a subscription you have already paid for, changes to your disadvantage only apply from the next renewal.

11. Final provisions

11.1 German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, you retain the protection of the mandatory provisions of the country of your habitual residence.

11.2 If you are a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction is Augsburg, Germany.

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

11.4 If any provision is invalid, the remaining provisions remain in effect.
