Your Chats Stay on Your Device

When you import a chat, Chatalyzer analyzes its text and media locally on your device. FiveSheep does not operate servers that receive your chats, messages, contacts, attachments, or the results of your analyses, and we cannot view or recover them.

What Chatalyzer Keeps

Chatalyzer does not keep the full text or media of an imported chat after the analysis is complete. Instead, it stores the results of the analysis on your device, such as statistics and summaries. These results are not intended to allow your chats to be reconstructed.

Some results may include short excerpts from your chats. For example, a result such as “Who said ‘I love you’ first?” may show the message it refers to, or part of it if the message is long. Results may also include participant names as they appear in the chat and the domain names of websites linked in the chat (but not the full links).

Chatalyzer does not delete the original chat export or backup you imported from. That data remains wherever you or the messaging service stored it.

Because the data Chatalyzer stores stays under your control, it is subject to the settings of your device. For example, depending on your settings, iOS or iPadOS may include app data in device backups, such as iCloud or computer backups. Such backups are handled by Apple or by you, not by FiveSheep.

Imported chats usually contain information about other people, such as the people you chat with. Please only import chats that you are entitled to use, and be considerate when sharing analysis results.

You can delete imported chats and their analysis results in the app at any time. Deleting Chatalyzer also removes its data from your device, although copies may remain in existing device backups.

Import from Backup

Chatalyzer offers an “Import from Backup” feature. When you use it, the app starts a local server that is bundled with the app and runs on your iPhone or iPad. This server is used to transfer backup data into Chatalyzer on your device. It is not operated by FiveSheep or any third party, and data transferred through it is not sent to FiveSheep or to third parties.

The server starts only when you choose “Import from Backup” and stops when you leave that screen. It does not run in the background otherwise. As with any local network service, we recommend using it only on networks you trust.

Website Icons

Chatalyzer groups links shared in your chats by website and can display an icon for each website. For this, Chatalyzer uses only the domain name (for example, example.org), not the full link. To display these icons, the app may download them from the Internet in two ways:

These requests are used to download icons, not to upload your chats, and they do not include full links or message content. However, like any Internet request, they necessarily reveal some information to the website or service you connect to, such as the domain name the icon is requested for, your IP address, and standard technical request information. These websites and services process this information under their own privacy policies, and FiveSheep does not receive or control their logs. See, for example, the Google Privacy Policy.

You can turn off the loading of website icons entirely, or turn off only the use of third-party icon services, in the app's settings.

Legal basis: Where this involves personal data, loading icons is necessary to provide the feature you use (Article 6(1)(b) GDPR) and is in our legitimate interest in providing a clear and useful app (Article 6(1)(f) GDPR). You can stop this processing at any time using the settings described above.

Analytics and Error Reporting

Chatalyzer does not include third-party analytics, advertising, tracking, or error reporting frameworks, and does not use your chats for advertising or to build profiles about you.

Apple may provide app developers with certain information, such as App Store statistics and, if you have chosen to share them with developers in your device settings, crash reports and usage data. This information is collected by Apple and governed by Apple's terms and privacy policy. You can change these sharing settings in your device's privacy settings.

Support Requests

If you contact us, for example by email, we receive the information you choose to send us, such as your email address and the content of your message. Please do not send us chat content unless it is necessary for your request. We use this information to respond to you and to improve Chatalyzer, and we keep it only as long as needed for these purposes or to comply with legal obligations.

Legal basis: Processing is necessary to respond to your request (Article 6(1)(b) GDPR) and for our legitimate interest in providing support and fixing problems (Article 6(1)(f) GDPR).

Sharing and Disclosure

We do not sell personal data. Since your chats are not transmitted to us, we cannot share them. We may disclose information we hold, such as support correspondence, where required by applicable law or necessary to establish, exercise, or defend legal claims.

Your Rights Under the GDPR

If the GDPR applies to you, you may have the right to:

Because your chats and analyses are stored only on your device, you can access and delete them directly in the app. To exercise your rights regarding any other data, email help@fivesheep.co.

You may also lodge a complaint with the Estonian Data Protection Inspectorate (Andmekaitse Inspektsioon) or the supervisory authority in the EU or EEA country where you live, work, or believe an infringement occurred.

Security

Chatalyzer is designed to keep your chats on your device. Your data is protected by the security features of your device, so we recommend keeping your device protected with a passcode and up to date. No method of electronic storage or transmission is completely secure, and we cannot guarantee absolute security.

Children's Privacy

Chatalyzer does not require an account and is not directed at children. We do not knowingly collect personal data from children. If you believe a child has sent us personal data, please contact us so we can delete it.

Apple Services

Apple may separately process information when it distributes Chatalyzer, handles a purchase, or provides iOS and iPadOS services. FiveSheep does not receive your payment card details. Apple's processing is governed by Apple's Privacy Policy.

Changes to This Policy

We may update this Privacy Policy when Chatalyzer or applicable law changes. We will publish the updated Policy on this page and change the “Last updated” date. If a change materially affects how we process personal data, we will provide additional notice where required by law.
