In the FAQ you can learn everything about tegolySIGN and digital signatures.

tegolySIGN and subscription

No, neither now nor in the future. The recipient is informed about the signature request by e-mail and only has to open the document and sign it. Recipients do not have to pay anything and do not need any special training. Signing works quite quickly and easily. Afterwards, both you and the recipient will receive a copy of the document.

With a 14-day trial subscription, you can fully test the app and discover the benefits of electronic signatures. If you decide not to continue the trial subscription within the 14-day period, we will not charge you.

Of course! We ensure compliance with strict US and EU electronic signature laws, use security mechanisms similar to those used in banks, provide two ways to authenticate the signer’s identity, and each transaction includes a comprehensive, court-approved audit trail. For more information, please see our Terms of Use.

The decision is up to you: The monthly subscriptions are only extended by one month at a time. With an annual subscription, you pay an annual fee and commit yourself for the next 12 months – but with a discount.

In the free trial version, the number of documents is limited to 10 and the number of users to 5. By starting a regular subscription, you can then add as many users and sign documents as you want.

Yes. Every signature made via our app meets the relevant security standards and is legally binding proof of contract.

Senders are persons who upload, sign and send documents via tegolySIGN or request signatures from other persons via tegolySIGN.

Someone who receives a signature request and responds to it is not considered the sender. Such users do not need a tegolySIGN account to sign documents and the process is free of charge for them.

You can choose – during or at the end of the free trial period – the subscription you want and the number of users. You will receive the invoice when the trial period has expired.

You can pay by credit card payments via the app or in the MS Store. Contact our team if you prefer another payment method.

Monthly subscriptions are billed on a monthly basis. For annual subscriptions you pay an annual fee in advance.

Yes, your subscription will be renewed automatically – unless you change or cancel your subscription. You can do this within seconds via the account settings.

Digital signature

A digital signature, also known as an electronic signature, is a legally binding way to sign a digital document such as a PDF, giving your consent.


The legal framework for electronic signatures is defined in the eiDAS Regulation (European Regulation on Electronic Identification and Trusted Services for Electronic Transactions) of the European Union. The requirements for the three different levels of electronic signatures are also defined there.

the simple electronic signature (EES)
the advanced electronic signature (FES)
the qualified electronic signature (QES)

The three types of eSignatures essentially differ in the level of security. Here they differ in probative value, that is, in the degree of confidence in the identity of the signer and in their proof that the signed document is actually the one presented.

However, it does not always make sense to use a multi-level authentication procedure when a simple or advanced signature can already have an appropriate level of validity and security.

Here is a brief explanation of the key differences between the three levels of eSignature and typical application areas.
The majority of electronic signatures created are “simple” signatures (EES) because they are unbeatable in terms of user-friendliness and ease of use.

There is no set requirement for the EES and it is not listed in the eIDAS. Here you can sign a document with 2 clicks, without identity verification and without consent. Thus, the signatories could theoretically simply deny that they signed the document. The EES can also be in the form of a scanned signature or the abbreviation scribbled on the terminal by the parcel delivery person.

With tegolySIGN, however, the evidential value for internal documents is strengthened, since we are dealing with signers who are already identified in the AD (Active Directory). For external signers, we store time and IP address in the certificate file. This increases the probative value and, in the event of litigation, the credibility of the signature and the document. In the certificate file, every step can thus be traced for internal and external signatories.

Sample documents
Here are some example of the EES:

  1. Orders/ Order confirmations
  2. Quotations
  3. Privacy statements
  4. General terms and conditions
  5. Contracts of sale of movable goods
  6. Service contracts
  7. Permanent employment contracts
  8. Confidentiality declarations
  9. Copyright declaration
  10. Survey confirmations (real estate)
  11. Transfer protocols (real estate)
  12. Mandate letters
  13. Property insurance
  14. Company insurances
Advanced electronic signature is recommended for financial transactions or signing documents where there may be significant legal risks.


Advanced electronic signature (FES) is subject to stricter identity verification criteria and thus has a higher evidential value, this is also specified in the eIDAS Regulation.

Therefore, the FES:

– be clearly associated with the signatory

– enable the identification of the signatory

– be created by means under the sole control of the signer, such as a phone, tablet, or PC;

– and ensure that the act to which it refers cannot be amended

An advanced electronic signature must be created using electronic signature creation data that the signer can use with a high degree of confidence under his sole control. In addition, the advanced electronic signature must be uniquely assigned to the signatory, enable the signatory’s identification, and be linked to the signed data in such a way that any subsequent change to the data can be detected. This is done either by means of the verification key assigned to the signature creator or, if necessary, by means of the verification keys captured during signature creation. biometric

Sample documents

– Partnership agreement (GbR, OHG, KG)
– Patent, trademark or copyright contracts
– Social security/pension documents
– Indefinite rental agreements without price escalation clause

Personal insurance, such as Life insurance, accident insurance or occupational disability insurance not covered by the Money Laundering Act
The qualified electronic signature (QES) is the highest form of electronic identification. However, it is only used in certain cases due to its high requirements.


Only documents with a qualified electronic signature can, in electronic form, replace a written form on paper required by law. In accordance with the European Directive, a qualified electronic signature is an advanced electronic signature based on a qualified certificate valid at the time of its generation and created using a secure signature creation device.

Sample documents

Official business: registration in the commercial register, advance VAT return to the tax office, annual financial statements, management reports, audit reports

  1. Receipts
  2. Fixed-term or part-time employment contracts
  3. Employee leasing contracts (temporary employment)
  4. Fixed-term leases with a term of more than one year (real estate)
  5. Graduated or indexed rental or lease agreements (real estate)
  6. Termination letter for rental or leasing contracts (real estate)
  7. Endowment policies with return of premiums
  8. Life insurance on the death of another person
  9. Brokerage power of attorney
  10. Consumer loan agreements
  11. SEPA direct debit mandates
  12. Bank account opening
  13. SIM card activation
  14. Electronic patient file
  15. e-tendering of public contracts
  16. Electronic waste verification procedure
A balance must be struck here, as the distinction between simple and advanced signatures is not sufficiently sharp. It is in the hands of the contracting parties to decide whether security takes precedence over user-friendliness or vice versa.

The following 3 steps for the decision serve as an aid:

– Consideration of regulations and law, e.g. what kind of contract should be signed and with whom
– Consideration of risks and opportunities: corporate image, impact on productivity, cost savings, etc.
– Choice of eSignature (EES, FES, QES), balancing user-friendliness and security needs.
