Posteo Transparency report
"We would like you to know how often authorities request user data from Posteo. For this reason we published a transparency report in May 2014, becoming the first German telecommunications provider to do so. Since then, we've regularly provided an impulse for more transparency and disclosed grievances in requests for information from authorities."
About the Transparency report
Important update
As a result of a ruling by the European Court of Justice (ECJ) on June 13, 2019, email services such as Posteo were no longer subject to the obligations of the German Telecommunications Act (TKG) between June 2019 and November 2021. Thus, the legal basis for any telecommunications monitoring (TKÜ) had ceased to exist. Posteo did not conduct any TKÜ during this period. The Federal Network Agency had removed Posteo from its list of telecommunications providers as a result of the ECJ ruling.
On 1 December 2021, a new TKG came into effect, which now also applies to email services. Our German FAQ section has already been updated accordingly and our English FAQ section is in the process of being adapted to the new TKG. There are still many references to the old TKG in the key topics, which we are gradually updating.
Welcome to the Posteo transparency report.
We would like you to know how often authorities request user data from Posteo. In this report, we show how often investigative authorities and intelligence services have requested data from Posteo – and how often we actually had to release data. In addition, you will find out how often these requests were formally correct and how many of the requests were illegal. The report covers all requests from authorities that Posteo received until the end of December 2022. We split the presentation of the numbers for 2019 and 2021 in two because email providers were no longer subject to German telecommunications law (TKG) from June 2019 until November 2021 after a decision made by the European Court of Justice.
Posteo publishes requests
Because many requests from authorities that reach Posteo do not comply with the legal provisions, we have continually devoted emphasis to the information process in our reports since 2015. Here we direct criticism at the chaotic conditions that rule in requests for user information under § 113 TKG. We reveal that in practice, grave security problems exist, there are regular breaches of the law and that deficiencies in controls are making the situation worse.
To prove this, we draw among other things on our own case documentation and publish examples of illegal requests from authorities. In addition, we publish our written communication with all the respective German federal state privacy officers as well as the justice ministries of the federal states. Thus you obtain an insight into our privacy-oriented background work that takes place at Posteo behind the scenes all year round.
We also occupy ourselves with the control instrument of the judicial reservation, which is in a state that in our view is no longer equitable in a constitutional state. In practice, all applications for surveillance measures were clearly approved. Though no statistics are kept on the efficacy of the judicial reservation, we have found numbers that prove this.
Our goals
In May 2014, Posteo became the first German telecommunications provider to publish a transparency report. We first had the permissibility of such a report checked with a legal opinion. With our move, we induced that in the meantime, other German providers also publish transparency reports – including, among others, Deutsche Telekom. With our transparency report, we would like to contribute to making existing grievances and legal realities public and allowing them to be debated.
We want something to change: despite that the government has been informed of some of the grievances for years, the situation has clearly not improved. Democratic control of state disclosure processes and surveillance measures in Germany must therefore be strengthened. We make proposals to this end in our transparency report. We call for the control organs to be better equipped, for example.
Answers to frequently asked questions on the legal bases and processes as well as how Posteo deals with requests from authorities are found in the "Background information and FAQs" section.
Requests for information:
Preliminary note: We are a privacy-oriented provider with a strong concept of data efficiency. We therefore possess neither personal data (user data like names and addresses), nor the IP addresses of our customers. If Posteo becomes required to release user data under a judicial ruling, authorities can therefore only receive content data (e.g. emails). In response to requests for personal information or IP addresses, we reply to the authorities that we do not possess the requested data.

Background information and frequently asked questions
General:
-
We want our customers to know how many and what type of requests for information we receive from authorities. We also want to make transparent how Posteo handles such inquiries. After the large-scale surveillance of citizens by intelligence agencies became known, it is more important than ever that providers publish transparency reports. They strengthen fundamental rights, informational self-determination and democracy as a whole.
-
In 2013, we received our first requests whatsoever from police authorities. For us it was clear that we wanted in future to publish a transparency report on requests from authorities following the model of American telecommunications companies.
Our lawyers pointed out, however, that the legal situation regarding this in Germany was not clear and for this reason, no German provider had published a transparency report until then. The legislator obligates German telecommunications providers with secrecy regarding requests for information in the Telecommunications Act (TKG) and the German G10 Act, among others. Therefore, prior to publication in May 2014, we had our attorneys prepare a comprehensive legal opinion. We needed to clarify the situation in advance, as violating the obligation of secrecy is punishable with up to five years’ imprisonment. The expert assessment that we commissioned determined that publishing purely statistical information that does not allow any inferences regarding individual cases is permitted. The Federal Ministry of Justice (Bundesministerium der Justiz) then also confirmed this in response to an enquiry from Christian Ströbele, MdB. Posteo then ultimately published the first transparency report by a German telecommunication provider on the 14th of May, 2014. -
We would like it to be become standard in Germany that telecommunications providers publish transparency reports. This form of transparency strengthens the possibility of democratic controls and the evaluation of surveillance measures. When we published the first report by a German telecommunications provider in 2014, the Deutsche Telekom followed a few hours later. In the mean time, a few other German providers have also published appropriate reports. We offer an exchange of experiences with other providers for which this comes into consideration.
Furthermore, we would like to instigate the provision of transparency reports by German providers in open data format, so that a transparent overall picture of requests for information can emerge. We publish our transparency report in an open, standardised exchange format (XML and JSON) so that any interested party has the ability to process and work statistically with the data we provide. An additional goal of our transparency reports is to reveal grievances in the information process and work towards improvement. -
For our transparency reports, we make the numbers available in a machine-readable format from now on. The data can then be read licence-free (CC0) and continue to be processed. In this way, individuals or companies that are interested can assess the data in a completely different form to us, for example, undertaking analysis and comparisons, if other providers also use this format to make the data in their transparency reports available. The key term here is “open data”. A civil society can debate better with such transparently available data at hand. In contrast with personal data, that has a high requirement for protection, such statistical data does not require protection, but rather should be available to all interested parties.
For the machine-readable form, we use a so-called plist/XML scheme that can also be used by other providers without issue and can be extended if required. The data for 2014 can be accessed as JSON or PLIST. -
In Germany, there are no such secret requests for which we can not provide statistical information. The Posteo transparency reports therefore cover all requests that we have received. In Posteo’s first four years of business (2009–2012) we did not receive any requests from authorities; until spring of 2013, Posteo was a very small provider. Reports exist for the years 2013 and 2014. Our reports encompass all requests from investigative authorities as well as all requests from intelligence services that have reached us.
-
Authorities request user information for various reasons: for example, to solve a crime or to pursue a suspicion of a minor breach of the law. Where there is a suspicion of serious crimes, investigative authorities are under certain circumstances entitled to receive emails or traffic data from providers. For this, however, they require a judicial ruling. For the release of personal information (for example, name and address) on the other hand, neither a judicial ruling nor the suspicion of a serious crime is necessary. With Posteo, no personal information can be requested as we do not collect our customers’ user information.
-
We first have each inquiry from a public authority carefully reviewed by our lawyers. We take the protection of our users' data very seriously. If our lawyers’ check determines that a request is not legally conforming, formally incorrect or the reach of a decision does not extend to the data requested by the authority, we lodge complaints. Posteo will never release data if there is doubt as to the correctness or legality of a ruling. We do not spare any expense or effort: we assure you that our lawyers, who are specialised in telecommunications, will do everything to defend your right to informational self-determination in the worst case scenario. We do not want to hinder (criminal) investigations, but we do want to ensure that the investigating authorities are actually entitled to receive the requested data. If the authorities are actually entitled to receive a Posteo user’s content data (for example, emails) due to a judicial ruling, then we must transfer such data to them. We are required to do this by law. Such requests are, however, very rare.
In most cases, authorities only request user information such as names and addresses, and as we do not save such data, we can not release it. -
In 2013 and 2014, we were only required to release data to investigative authorities in individual cases after a judicial ruling (see the transparency reports for the years 2013 and 2014). Altogether, three email accounts were affected, for which there were sometimes multiple requests (e.g. account seizure as well as TKÜ). In each case, the authorities had presented a formally correct ruling for the ongoing surveillance of an email account or an email account’s seizure. Release of the data occurred only after a thorough check by our lawyers. In the years prior to 2013 we did not receive any requests from authorities.
-
Yes. We go into this in the transparency report under "Authorities illegally request dynamic IP addresses".
-
No, we are not allowed to inform affected users. That would make us liable for prosecution. German telecommunications providers are bound to secrecy regarding most requests for information from authorities by various laws (among others, the Telecommunications Act (TKG) and the G10 Act). This has been regulated by statute in order to preclude ongoing investigations from being jeopardised.
Types of data, requests and legal bases:
-
Your personal data (such as your name and address or bank account number) are called "inventory data" in the texts of the laws. When you become the customer of a telecommunications company, the company (TKG § 111) must store the following personal data for you: your name, your date of birth, and your address. When connections are made, your telephone and fax numbers, as well as (depending on the kind of connection) further data such as device numbers, connection numbers or data about the contract’s beginning and end must also be saved. For email providers, there is a special regulation – they are allowed to refrain from collecting your personal data (§ 111 TKG), and are then not required to save it. Posteo makes use of this regulation. We do not need your personal data – not even for billing purposes (see: Anonymous payment with Posteo). If email providers want to save your personal data, they must (§ 111 TKG) save the following data: the name of the email mailbox, the name of the holder of the email's mailbox, and this person’s address. If the provider stores your bank data in connection with your mailbox, such data are also existent inventory data.
-
The legislator even explicitly calls on companies (§ 3a of the German Federal Data Protection Act) to avoid saving personal data whenever possible:
Data avoidance and data minimisation: The collection, processing and use of personal data and the selection and design of data processing systems must be oriented to the goal of collecting, processing and using as little personal data as possible. In particular, personal data are to be made anonymous or pseudonymous, to the extent that this is possible according to the intended purpose and does not require disproportionate efforts in relation to the protective purpose that is sought.
Bundesdatenschutzgesetz § 3aOur design of Posteo has been guided by this requirement.
We work as economically with data as possible, to protect our users as best as possible: only data that is not collected, can with 100% certainty not be stolen or misused. Meanwhile, countless cases have become known in which criminals have stolen customers’ data from companies. For example, to access bank data and to commit fraud. Our concept employs maximal privacy: we therefore do not collect any personal data, and have made all payment processes anonymous. -
Authorities can receive no inventory data from Posteo, because we don’t collect it.
In general, inventory data may be queried from providers by numerous authorities and other authorised parties upon suspicion of a minor misdemeanour (such as a parking violation or a noise complaint). There is no substantive review or requirement of a judicial decision. The law allows for the identification of internet users for the prosecution of misdemeanours of any type. When providers with more than 100,000 participants collect inventory data, they must make it automatically available for query. According to the German Federal Network Agency (Bundesnetzagentur), about 6.92 million requests producing 34.3 million results were carried out in this manner in 2014. (Source: 2014 Activity Report of the Federal Network Agency) -
No. In the practice of inventory data requests under § 113 TKG there exist grave security problems and deficiencies. Please read our transparency report for this year, which concerns itself with this subject.
-
Traffic data are data that arise in telecommunications activity. Such data document, for example, the point in time at which an email was exchanged between two electronic mailboxes. Traffic data that accumulate at email providers are, for example:
- information regarding when (point in time) an email was sent from a specific email address to another email address
- information regarding the IP address from which the email was sent
Such data are stored in the email provider’s so-called "log files". They may use such data only for the following two purposes:
- for detecting, isolating and eliminating technical errors (§ 100, para. 1 TKG), for example, when sending or receiving emails
- for detecting misuse of the system (§ 100, para. 3 TKG), for example, by spammers.
-
Traffic data are subject to the protection of telecommunications secrecy. It is therefore prohibited to release traffic data in response to simple inquiries from authorities. Law enforcement agencies need a court order to query traffic data with us. This is only granted by a judge if there is suspicion of a serious criminal act. German law also does not permit traffic data to be stored separately for the purpose of law enforcement (in particular, data retention). Only data that is lawfully stored for operational reasons may be used to issue information. This means that public authorities are not allowed to demand that we collect additional traffic data of our users. When you visit our site and log in to your mailbox, we do not store your IP address, for example.
-
No. We can not collect and save these because we do not require them for operational purposes. We therefore do not possess IP addresses in connection to any accounts and can not release them as a result.
-
Telecommunications secrecy is a fundamental right and, just like mail and postal secrecy, is subject to the protection of Article 10 of the German Basic Law (Grundgesetz). It stipulates that citizens have a right vis-à-vis the state for their private communications to be shielded so that facts and thoughts can be exchanged and passed on without this being observed from the outside. Both specific content (phone calls, emails) and the traffic data of telecommunications are subject to telecommunications secrecy. However, this may also be limited – the cases in which limitations are possible are governed in the German Code of Criminal Procedure (Strafprozessordnung or StPO) and the G10 Act. With law enforcement actions, a monitoring of telecommunications for a certain period of time may be ordered if there is a justified suspicion of a serious criminal act (§ 100a, StPO). The monitoring must be ordered by a judge or – if there is a danger in delay – by the Public Prosecutor's Office. Moreover, under § 100g of the StPO, the communication of traffic data may be ordered in individual cases. The G10 Act stipulates when services such as the State Offices of the Protection of the Constitution and the Office for Military Counter-Intelligence Service are entitled to monitor telecommunications. If monitoring is ordered, the telecommunications provider must provide the authorised public authorities with a copy of the telecommunications activity. The person affected by such monitoring must be informed of the measure that was conducted (by the authorities) as soon as the "purpose of the measure" permits this. The authorities must destroy the data that they received during the access.
-
Content data are nothing more than the "content" of your communications – your emails. The German legislator has placed a hurdle on the release of content that is quite high: your emails are subject to telecommunications secrecy. As we never voluntarily release mailboxes (§ 94, para. 1, StPO) but always formally object to inquiries, a seizure under criminal law of a Posteo mailbox must be ordered by a judge (§ 94, para. 2, StPO, § 98, para. 1, sent. 1 or para. 2, sent. 1, StPO). Moreover, a TKÜ order under criminal law for monitoring a mailbox for a certain period of time may be effected only for certain serious criminal acts. Every court order must be presented to us (the provider) by the public authorities, and is reviewed by our attorneys for scope and formal correctness before we pass on any data. The customer affected may not be informed of a TKÜ order. That would make us liable for prosecution.
Please read our transparency report for this year, which concerns itself with this subject. -
If there is a seizure under criminal law of a Posteo mailbox (§ 94, para. 2, StPO, § 98, para. 1, sent. 1 or para. 2, sent. 1, StPO), we are obliged to pass on all emails that were in the relevant electronic mailbox at the point in time of the seizure. If there is a TKÜ order for monitoring a mailbox, we are obliged to divert to the authorised public authorities all emails that are received in or are sent from the relevant mailbox, beginning with the time of the order. Previously stored emails are not affected by a TKÜ. However, both measures – seizure and ongoing monitoring – may be combined with each other.
Common questions on the release of data: encryption, passwords and “eavesdropping interfaces”
-
There is no SINA box at Posteo yet. A SINA box is not an eavesdropping interface that allows authorities access to data at a provider. More information on the SINA box and the way German email providers transmit data to authorities can be found in our blog post on this topic. In the telecommunication surveillance act, there is a requirement for telecommunications providers with at least 10,000 members to install a special computer (SINA box). For us, it is not possible to determine without doubt how many members our service has, as we do not collect any user information from our users. We only know the number of email accounts. The Bundesnetzagentur assumes that we have meanwhile crossed the threshold. We have therefore intensively occupied ourselves with this topic during the last year. This resulted in various questions that we are now pursuing. As soon as there is any news on this, we will report it in our blog.
-
No, unlike in the United States or the UK (for example), this is not possible in Germany. There are no laws in Germany that could oblige us to break encryption. We had this clarified through our lawyers before developing encryption features such as Posteo crypto mail storage. This, for example, is technically designed such that Posteo can not remove the encryption applied by the user – only the user can do this themselves. If a user furnishes data with end-to-end encryption, this can not be removed by the respective provider.
-
No. There is no legal basis for this in Germany.
-
No. We do not store your password in plain text, but only as so-called "salted hash values". Thus, we do not know your password, and cannot release it either to you or to any third party. You can find more information on the encryption of passwords at Posteo on our encryption topic page.
-
No. Your mobile number is encrypted in our database, again, as a "salted hash". We do not know your mobile phone number, and cannot release it to any third party. You can find more information about encryption of mobile telephone numbers at Posteo on our encryption explanation page.
-
The government’s draft law for the planned reintroduction of data retention ("Gesetz zur Einführung einer Speicherpflicht und einer Höchstspeicherfrist für Verkehrsdaten") stipulates that the entire area of email should be exempt from being saved. This means that if it remains like this, Posteo is not counted among the obligated parties.
Independent of this, we reject data retention in principle. We are currently following the situation very closely. -
If we are required by a judicial ruling to release an email account, we need to release content data, as it exists. Email data saved with us that has been encrypted by the customer, e.g. using our crypto mail storage or with the help of end-to-end encryption, can not be decrypted by Posteo in retrospect.
If emails are encrypted, they will therefore be released encrypted.
