+<p>The Delta Chat project underwent three independent security audits in the last
+years:</p>
+
+<ul>
+  <li>
+    <p>In 2019, <a href="https://includesecurity.com">Include Security</a> analyzed Delta
+Chat’s <a href="https://github.com/rpgp/rpgp">PGP</a> and
+<a href="https://github.com/RustCrypto/RSA">RSA</a> libraries.
+It found no critical issues,
+but two high-severity issues that we subsequently fixed.
+It also revealed one medium-severity and some less severe issues,
+but there was no way to exploit these vulnerabilities in the Delta Chat implementation.
+Some of them we nevertheless fixed since the audit was concluded.
+You can read the <a href="../assets/blog/2019-first-security-review.pdf">full report here</a>.</p>
+  </li>
+  <li>
+    <p>In 2020, <a href="https://includesecurity.com">Include Security</a> analyzed Delta
+Chat’s Rust <a href="https://github.com/deltachat/deltachat-core-rust/">core</a>,
+<a href="https://github.com/async-email/async-imap">IMAP</a>,
+<a href="https://github.com/async-email/async-smtp">SMTP</a>, and
+<a href="https://github.com/async-email/async-native-tls">TLS</a> libraries.
+It did not find any critical or high-severity issues.
+The report raised a few medium-severity weaknesses -
+they are no threat to Delta Chat users on their own
+because they depend on the environment in which Delta Chat is used.
+For usability and compatibility reasons,
+we can not mitigate all of them
+and decided to provide security recommendations to threatened users.

+  </li>
+  <li>
+    <p>Beginning 2023, <a href="https://cure53.de">Cure53</a> analyzed both the transport encryption of
+Delta Chat’s network connections and a reproducible mail server setup as

+
+<ul>
+  <li>
+    <p>In 2019, <a href="https://includesecurity.com">Include Security</a> analyzed Delta
+Chat’s <a href="https://github.com/rpgp/rpgp">PGP</a> and

+It found no critical issues,

+<a href="https://github.com/async-email/async-imap">IMAP</a>,
+<a href="https://github.com/async-email/async-smtp">SMTP</a>, and

+It did not find any critical or high-severity issues.
+The report raised a few medium-severity weaknesses -
+they are no threat to Delta Chat users on their own
+because they depend on the environment in which Delta Chat is used.
+For usability and compatibility reasons,
+we can not mitigate all of them
+and decided to provide security recommendations to threatened users.

+<p>The best way to ensure every message is encrypted,
+and metadata deleted as quickly as possible
+is creating a verified group and turning on
+self-destructing messages.</p>
+
+<p>Verified groups are always encrypted and protected against <a href="https://en.wikipedia.org/wiki/Man-in-the-middle_attack">MITM
+attacks</a>.</p>
+
+<p>Metadata can’t be encrypted, as the server needs to know where to deliver your
+messages. But turning on “self-destructing messages” deletes the messages on
+the server after they were delivered.</p>
+
+<p>If you need the messages on your device, but not on the server, you can also
+agree in the group to turn on <a href="#what-happens-if-i-turn-on-delete-old-messages-from-server">“delete messages from server
+automatically”</a>.</p>
+
+<p>If you want to protect a 1:1 conversation like this, you should create a
+verified group with only 2 people. If the other person loses their device but
+not their account, you can still communicate in the 1:1 chat. (<a href="#what-is-the-difference-between-verified-groups-and-11-chats-with-verified-contacts">Read more</a>)</p>

+<p>The Delta Chat project underwent three independent security audits in the last
+years:</p>
+
+<ul>
+  <li>
+    <p>In 2019, <a href="https://includesecurity.com">Include Security</a> analyzed Delta
+Chat’s <a href="https://github.com/rpgp/rpgp">PGP</a> and
+<a href="https://github.com/RustCrypto/RSA">RSA</a> libraries.
+It found no critical issues,
+but two high-severity issues that we subsequently fixed.
+It also revealed one medium-severity and some less severe issues,
+but there was no way to exploit these vulnerabilities in the Delta Chat implementation.
+Some of them we nevertheless fixed since the audit was concluded.

+  <li>
+    <p>In 2020, <a href="https://includesecurity.com">Include Security</a> analyzed Delta
+Chat’s Rust <a href="https://github.com/deltachat/deltachat-core-rust/">core</a>,
+<a href="https://github.com/async-email/async-imap">IMAP</a>,
+<a href="https://github.com/async-email/async-smtp">SMTP</a>, and
+<a href="https://github.com/async-email/async-native-tls">TLS</a> libraries.
+It did not find any critical or high-severity issues.
+The report raised a few medium-severity weaknesses -
+they are no threat to Delta Chat users on their own
+because they depend on the environment in which Delta Chat is used.
+For usability and compatibility reasons,
+we can not mitigate all of them
+and decided to provide security recommendations to threatened users.

+<p>The Delta Chat project underwent three independent security audits in the last
+years:</p>
+
+<ul>
+  <li>
+    <p>In 2019, <a href="https://includesecurity.com">Include Security</a> analyzed Delta
+Chat’s <a href="https://github.com/rpgp/rpgp">PGP</a> and
+<a href="https://github.com/RustCrypto/RSA">RSA</a> libraries.
+It found no critical issues,
+but two high-severity issues that we subsequently fixed.
+It also revealed one medium-severity and some less severe issues,
+but there was no way to exploit these vulnerabilities in the Delta Chat implementation.
+Some of them we nevertheless fixed since the audit was concluded.
+You can read the <a href="../assets/blog/2019-first-security-review.pdf">full report here</a>.</p>
+  </li>
+  <li>
+    <p>In 2020, <a href="https://includesecurity.com">Include Security</a> analyzed Delta
+Chat’s Rust <a href="https://github.com/deltachat/deltachat-core-rust/">core</a>,
+<a href="https://github.com/async-email/async-imap">IMAP</a>,
+<a href="https://github.com/async-email/async-smtp">SMTP</a>, and
+<a href="https://github.com/async-email/async-native-tls">TLS</a> libraries.
+It did not find any critical or high-severity issues.
+The report raised a few medium-severity weaknesses -
+they are no threat to Delta Chat users on their own
+because they depend on the environment in which Delta Chat is used.
+For usability and compatibility reasons,
+we can not mitigate all of them
+and decided to provide security recommendations to threatened users.
+You can read the <a href="../assets/blog/2020-second-security-review.pdf">full report here</a>.</p>
+  </li>
+  <li>
+    <p>Beginning 2023, <a href="https://cure53.de">Cure53</a> analyzed both the transport encryption of
+Delta Chat’s network connections and a reproducible mail server setup as

+<p>The Delta Chat project underwent three independent security audits in the last
+years:</p>
+
+<ul>
+  <li>
+    <p>In 2019, <a href="https://includesecurity.com">Include Security</a> analyzed Delta
+Chat’s <a href="https://github.com/rpgp/rpgp">PGP</a> and
+<a href="https://github.com/RustCrypto/RSA">RSA</a> libraries.
+It found no critical issues,
+but two high-severity issues that we subsequently fixed.
+It also revealed one medium-severity and some less severe issues,
+but there was no way to exploit these vulnerabilities in the Delta Chat implementation.
+Some of them we nevertheless fixed since the audit was concluded.
+You can read the <a href="../assets/blog/2019-first-security-review.pdf">full report here</a>.</p>
+  </li>
+  <li>
+    <p>In 2020, <a href="https://includesecurity.com">Include Security</a> analyzed Delta
+Chat’s Rust <a href="https://github.com/deltachat/deltachat-core-rust/">core</a>,
+<a href="https://github.com/async-email/async-imap">IMAP</a>,
+<a href="https://github.com/async-email/async-smtp">SMTP</a>, and
+<a href="https://github.com/async-email/async-native-tls">TLS</a> libraries.
+It did not find any critical or high-severity issues.
+The report raised a few medium-severity weaknesses -
+they are no threat to Delta Chat users on their own
+because they depend on the environment in which Delta Chat is used.
+For usability and compatibility reasons,
+we can not mitigate all of them
+and decided to provide security recommendations to threatened users.
+You can read the <a href="../assets/blog/2020-second-security-review.pdf">full report here</a>.</p>
+  </li>
+  <li>
+    <p>Beginning 2023, <a href="https://cure53.de">Cure53</a> analyzed both the transport encryption of
+Delta Chat’s network connections and a reproducible mail server setup as

-space ;-)</li>

-way, <em>all</em> e-mails will be deleted from the server after that timeframe.</li>
-  <li>Note that if you use Delta Chat on more than one device, you should leave the
-messages on the server, until the other device could download them, too. In
-this case, you should set auto-delete to “after a day” or something similar,
-depending on how often you turn on the other device.</li>
+  <li>За умовчанням Delta Chat зберігає всі повідомлення локально на вашому пристрої.

-right click on the map and describe a location, which is sent to the chat as
-a message, but also appears on the map.</li>
+  <li>Ви можете ввімкнути потокове передавання місцезнаходження в розділі «експериментальні функції» в розширених налаштуваннях.</li>
+  <li>Тепер, якщо ви хочете поділитися своїм місцезнаходженням у чаті, перейдіть до «прикріпити» та виберіть “Місцезнаходження”. Тепер ви можете встановити часові рамки, протягом яких ваше місцезнаходження транслюється вашим партнерам у чаті від 5 хвилин до 6 годин.</li>
+  <li>Коли ваше місцезнаходження змінюється, інші учасники чату можуть побачити його на карті в чат.</li>
+  <li>Щоб бачити карту та місцезнаходження інших, потрібно ввімкнути цю функцію у розширених налаштуваннях.</li>
+  <li>Ця функція не надасть доступу до вашого місцезнаходження нікому, крім ваших співрозмовників в чаті. <em>Але:</em> щоб показати карту, нам потрібно завантажити фрагменти карти з mapbox.com, тому, якщо ви <em>переглядаєте</em> карту, mapbox.com запитує карту конкретної області. Якщо це загроза конфіденційності для вас, ця функція може бути не для вас. Ми працюємо над пошуком децентралізованої альтернативи для Mapbox.</li>
+  <li>На комп’ютері ОС зазвичай не може визначити ваше місцезнаходження. Натомість ви можете клацнути правою кнопкою миші на карті та надсилати до чату як повідомлення, яке також з’являється на карті.</li>

+
+<p>The Delta Chat project underwent three independent security audits in the last
+years:</p>
+
+<ul>
+  <li>
+    <p>In 2019, <a href="https://includesecurity.com">Include Security</a> analyzed Delta
+Chat’s <a href="https://github.com/rpgp/rpgp">PGP</a> and
+<a href="https://github.com/RustCrypto/RSA">RSA</a> libraries.
+It found no critical issues,
+but two high-severity issues that we subsequently fixed.
+It also revealed one medium-severity and some less severe issues,
+but there was no way to exploit these vulnerabilities in the Delta Chat implementation.
+Some of them we nevertheless fixed since the audit was concluded.
+You can read the <a href="../assets/blog/2019-first-security-review.pdf">full report here</a>.</p>
+  </li>
+  <li>
+    <p>In 2020, <a href="https://includesecurity.com">Include Security</a> analyzed Delta
+Chat’s Rust <a href="https://github.com/deltachat/deltachat-core-rust/">core</a>,
+<a href="https://github.com/async-email/async-imap">IMAP</a>,
+<a href="https://github.com/async-email/async-smtp">SMTP</a>, and
+<a href="https://github.com/async-email/async-native-tls">TLS</a> libraries.
+It did not find any critical or high-severity issues.
+The report raised a few medium-severity weaknesses -
+they are no threat to Delta Chat users on their own
+because they depend on the environment in which Delta Chat is used.
+For usability and compatibility reasons,
+we can not mitigate all of them
+and decided to provide security recommendations to threatened users.
+You can read the <a href="../assets/blog/2020-second-security-review.pdf">full report here</a>.</p>
+  </li>
+  <li>
+    <p>Beginning 2023, <a href="https://cure53.de">Cure53</a> analyzed both the transport encryption of
+Delta Chat’s network connections and a reproducible mail server setup as

+<p>The Delta Chat project underwent three independent security audits in the last
+years:</p>
+
+<ul>
+  <li>
+    <p>In 2019, <a href="https://includesecurity.com">Include Security</a> analyzed Delta
+Chat’s <a href="https://github.com/rpgp/rpgp">PGP</a> and
+<a href="https://github.com/RustCrypto/RSA">RSA</a> libraries.
+It found no critical issues,
+but two high-severity issues that we subsequently fixed.
+It also revealed one medium-severity and some less severe issues,
+but there was no way to exploit these vulnerabilities in the Delta Chat implementation.
+Some of them we nevertheless fixed since the audit was concluded.

+  </li>
+  <li>
+    <p>In 2020, <a href="https://includesecurity.com">Include Security</a> analyzed Delta
+Chat’s Rust <a href="https://github.com/deltachat/deltachat-core-rust/">core</a>,
+<a href="https://github.com/async-email/async-imap">IMAP</a>,
+<a href="https://github.com/async-email/async-smtp">SMTP</a>, and
+<a href="https://github.com/async-email/async-native-tls">TLS</a> libraries.
+It did not find any critical or high-severity issues.
+The report raised a few medium-severity weaknesses -
+they are no threat to Delta Chat users on their own
+because they depend on the environment in which Delta Chat is used.
+For usability and compatibility reasons,
+we can not mitigate all of them
+and decided to provide security recommendations to threatened users.

+    <p>Beginning 2023, <a href="https://cure53.de">Cure53</a> analyzed both the transport encryption of
+Delta Chat’s network connections and a reproducible mail server setup as
