PRIVACY POLICY
Parail Privacy Policy
Effective: October 27, 2026 / Last updated: November 3, 2026
myulabs ("we" or "us") sets out this Privacy Policy ("this Policy") for how user information is handled in the iOS app "Parail" ("the App").
The App is a web browser. We have no server and there are no accounts. Your browsing history, bookmarks and similar data are stored only on your device (and, if you turn on sync, in your own iCloud). We never collect or view them.
This English version is a translation. If there is any difference between this version and the Japanese version, the Japanese version prevails.
In short
- No data is sent to our servers.
- No advertising, analytics or crash-reporting tools are built in.
- Your device communicates directly with websites, search engines and AI services.
1. Information stored on your device
To work as a browser, the App stores the following information on your device. We never collect it.
- Open tabs, workspaces, browsing history, bookmarks, favorite sites, pairs (saved split views), per-site settings and other settings
- Followed sites, the titles and text of articles received, and their read, favorite and saved status
- Website data stored by websites, such as cookies
- Downloaded files (available in the Files app under "On My iPhone" → "Parail")
- Site icons (favicons)
If you create profiles, website data (such as cookies and login state) is stored separately for each profile on your device. Deleting a profile also deletes its website data.
Pages viewed in private tabs are not saved to your browsing history. Cookies and other data from private tabs are not saved to the device and are discarded when you close the last private tab.
2. Communication with websites
When you open a page, the App communicates directly between that website and your device, never through our servers. As with any browser, the information needed for communication (such as your IP address) is sent to the website. Each website handles that information under its own policies.
The App also accesses websites directly from your device in these cases:
- To get the icons (favicons) shown for tabs and bookmarks
- To check followed sites for new articles, and to fetch article pages so their text can be shown in an easy-to-read view (no cookies are sent or saved)
New articles from followed sites may also be checked while the App is not open, using iOS Background App Refresh. You can turn this off in the iPhone Settings app under General → Background App Refresh. Only if you turn on "Notify new articles" in Settings does the App tell you about new articles with on-device (local) notifications. We do not use any server for notifications.
Ad and tracker blocking uses lists bundled with the App (based on EasyList / EasyPrivacy and the AdGuard Japanese filter) and is decided on your device, without any outside communication. To keep the lists up to date, the App downloads the list files from parail.app about once a week (download only; no browsing history or device information is sent).
3. Search and translation
Search terms you type in the address bar are sent to the search engine you choose in Settings (Google, Bing, DuckDuckGo, Ecosia, Yahoo! JAPAN, or one you specify).
If you translate a page, the URL of the page is sent to Google Translate (Google LLC).
Suggestions shown while you type are made from your browsing history and bookmarks on your device. What you type is not sent anywhere for suggestions.
4. AI panel
The AI panel shows the web pages of the AI service you choose (ChatGPT, Claude or Gemini) inside the App. You sign in with your own account.
- Your login is handled as cookies and similar data that each service's page stores on your device. We never collect or store your login information.
- If you use "Summarize" or "Translate", the title, URL and text of the current page (up to 6,000 characters; for translation, the selected text) are entered into the chosen AI service's input field. When you send it, the content is sent to the AI service.
- If you ask AI a question from the App, the title, URL and text of the current page and of the tabs you choose (about 6,000 characters in total) are sent to the AI service along with your question. You choose the tabs each time.
- If you use "Summarize with AI" on a followed article, the article's title, URL and text are sent to the AI service in the same way.
- Each AI service handles information under the policies of its provider (OpenAI, Anthropic or Google).
5. iCloud sync
When "Sync with iCloud" is on in Settings, the following information is saved in Apple's iCloud (in your own account) and synced between devices that use the same Apple Account:
- Favorite sites, pairs, bookmarks, rail layout, per-site settings, profile names and workspaces
- Open tabs (if tab sync is turned on in Settings)
- Followed sites, categories, and read, favorite and saved status
Browsing history, website data (cookies and login state), private tabs and downloaded files are not synced. We cannot view this data, and it is never stored on our servers. You can turn sync off in Settings at any time.
6. Face ID lock
If you lock private tabs or the whole App with Face ID (or Touch ID or your passcode), authentication is performed on your device by Apple's system. Neither the App nor we receive any face or fingerprint information.
7. Other features
- Read aloud uses on-device speech synthesis. The text being read is not sent anywhere.
- Page URLs sent to the App from another app's share menu are passed to the App on your device.
- In-app purchases are processed by Apple Inc. (StoreKit). We never receive your name or payment information.
8. Sharing with third parties
We do not collect your information, so we never provide or sell it to third parties. The communication described in sections 2–4 happens directly from your device to each website or service, in response to your actions.
9. What the App does not do
- Collect the advertising identifier (IDFA), or track you for advertising or across apps
- Use analytics or crash-reporting tools
- Send or store your browsing history, bookmarks, what you type or similar data on our servers
- Sell your data
10. Deleting data
You can delete your browsing history and website data in the App's Settings. Deleting the App from your device erases the data stored on the device. To delete data synced to iCloud, turn off sync and then delete it in the iPhone Settings app under (your name) → iCloud.
Because we do not hold any of your personal data, we have no procedure for requests regarding "retained personal data" under Japan's Act on the Protection of Personal Information.
11. Children
The App does not knowingly collect personal information from children. Because the App can be used to browse any website, children should use it under the responsibility of a parent or guardian.
12. Changes to this Policy
We may revise this Policy as needed. If there are important changes, we will let you know in the App or on this page. The revised Policy takes effect when it is posted on this page.
13. Contact
