<h1>Privacy Policy for Rosetta</h1>
|
|
<p class="muted">Last updated: May 22, 2026</p>
|
|
|
|
<p>
|
|
Rosetta IM is operated by ROSETTA CLOUD SERVICES LIMITED ("Rosetta",
|
|
"we", "us", or "our"). This Privacy Policy explains how we handle
|
|
information when you use Rosetta, our end-to-end encrypted messaging
|
|
application, and our website at https://rosetta.im.
|
|
</p>
|
|
|
|
<h2>1. Information We Collect</h2>
|
|
<p>
|
|
Rosetta is designed to minimize data collection. Registration does not
|
|
require a phone number, email address, or real name. The app uses
|
|
cryptographic keys and technical identifiers needed to operate the
|
|
service.
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Account and cryptographic data: public keys, account identifiers, and
|
|
related technical data needed to identify users and deliver encrypted
|
|
messages. Private keys are intended to remain on your device.
|
|
</li>
|
|
<li>
|
|
Encrypted messages and media in transit: message text, files, and
|
|
media are encrypted before they are sent. Our servers are designed to
|
|
relay encrypted payloads and encrypted message keys, not to read
|
|
message contents.
|
|
</li>
|
|
<li>
|
|
Device and app data: app version, operating system, platform,
|
|
architecture, update request data, IP address, timestamps, and server
|
|
logs needed for security, reliability, abuse prevention, and update
|
|
delivery.
|
|
</li>
|
|
<li>
|
|
Support communications: if you contact us, we may process your email
|
|
address, message content, and any information you choose to provide.
|
|
</li>
|
|
</ul>
|
|
|
|
<h2>2. Information We Do Not Collect for Advertising</h2>
|
|
<p>
|
|
We do not use third-party advertising SDKs, advertising trackers, or
|
|
cross-app tracking. We do not sell your personal information.
|
|
</p>
|
|
|
|
<h2>3. How We Use Information</h2>
|
|
<p>We use information only to:</p>
|
|
<ul>
|
|
<li>provide, maintain, and secure Rosetta;</li>
|
|
<li>route encrypted messages between users;</li>
|
|
<li>deliver app updates and downloads;</li>
|
|
<li>detect abuse, prevent fraud, and protect service integrity;</li>
|
|
<li>respond to support requests;</li>
|
|
<li>comply with legal obligations.</li>
|
|
</ul>
|
|
|
|
<h2>4. End-to-End Encryption</h2>
|
|
<p>
|
|
Rosetta is designed so that message content is encrypted before it
|
|
reaches our servers. Our servers are not intended to have access to
|
|
decrypted message contents or decrypted media. Messages are stored on
|
|
users' devices rather than as readable message history on our servers.
|
|
</p>
|
|
|
|
<h2>5. Sharing of Information</h2>
|
|
<p>We may share limited information only with:</p>
|
|
<ul>
|
|
<li>infrastructure and hosting providers that help us operate Rosetta;</li>
|
|
<li>professional advisers, if necessary;</li>
|
|
<li>
|
|
authorities or other parties when required by law or to protect rights,
|
|
safety, and security.
|
|
</li>
|
|
</ul>
|
|
<p>
|
|
Any service provider that processes user data for us must protect it
|
|
consistently with this Privacy Policy.
|
|
</p>
|
|
|
|
<h2>6. Retention</h2>
|
|
<p>
|
|
Encrypted message data in transit is processed only as needed to deliver
|
|
the service. Technical logs and support communications are retained only
|
|
for as long as reasonably necessary for security, reliability, support,
|
|
legal, and operational purposes.
|
|
</p>
|
|
|
|
<h2>7. Your Choices and Rights</h2>
|
|
<p>
|
|
Depending on where you live, you may have rights to access, correct,
|
|
delete, or object to certain processing of your personal information. To
|
|
make a request, contact us at admin@rosetta.im.
|
|
</p>
|
|
<p>
|
|
Because Rosetta minimizes account data and uses cryptographic
|
|
identifiers, some requests may require you to provide information that
|
|
helps us verify control of the relevant account or keys.
|
|
</p>
|
|
|
|
<h2>8. Children</h2>
|
|
<p>
|
|
Rosetta is not directed to children under 13, or the minimum age required
|
|
in your jurisdiction. If we learn that we have collected personal
|
|
information from a child without required consent, we will take
|
|
appropriate steps to delete it.
|
|
</p>
|
|
|
|
<h2>9. International Transfers</h2>
|
|
<p>
|
|
ROSETTA CLOUD SERVICES LIMITED may process information in countries other
|
|
than where you live. Where required, we use appropriate safeguards for
|
|
international transfers.
|
|
</p>
|
|
|
|
<h2>10. Security</h2>
|
|
<p>
|
|
We use technical and organizational measures designed to protect
|
|
information. No system is perfectly secure, and users are responsible for
|
|
protecting their devices, private keys, and account access.
|
|
</p>
|
|
|
|
<h2>11. Changes to This Policy</h2>
|
|
<p>
|
|
We may update this Privacy Policy from time to time. If we make material
|
|
changes, we will update the "Last updated" date and, where appropriate,
|
|
provide additional notice.
