Privacy Policy

Last updated: November 10, 2026

This Privacy Policy explains how AH QR Scan & Generate ("we", "us", "the app") collects, uses and protects information when you use our website at ahapp.site and our Android app.

1. Camera access

The scanner asks for permission to use your camera only when you open the Scan tab. Camera images are processed entirely on your device to decode QR codes. We never record, upload or store camera images or video.

2. Scan and generation history

• If you are not signed in, your history is saved only in your browser's local storage on your device.
• If you create an account and sign in, your history (the decoded text and saved QR images) is stored in your Google Drive app-data folder for Google sign-in accounts, or in Supabase for email/password accounts, so you can access it on other devices. Only you can read your own records.
• You can delete individual items or clear your history at any time from the History tab.

3. Account information

Supabase provides account authentication and cloud storage for email/password accounts. Google sign-in accounts store new QR history, notes, profile details, favorites, and folders in a private Google Drive app-data folder after permission is granted. Existing Supabase records are copied to Drive once; older Supabase copies remain until separately removed. Drive data can be removed through the app or Google Drive settings. The app requests only its own app-data scope, not access to your other Drive files. Supabase processes your email address and password for sign-in; passwords are stored as hashes, not readable passwords. We do not sell, rent or share your email address with third parties for marketing.

4. Advertising and cookies

When advertising is enabled, we use Google AdSense on the website and Google AdMob in the Android app. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.

• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this and/or other sites on the Internet.
• You may opt out of personalized advertising by visiting Google Ads Settings, or opt out of some third-party vendors' cookies at www.aboutads.info.
• Learn more in How Google uses information from sites that use its services.

For visitors in the European Economic Area, the UK and Switzerland, Google's consent message is shown when a message for this site is published in AdSense Privacy & messaging. Ads and data use follow the choices made in that message and applicable settings. You can reopen your choices below when the consent settings are available.

Optional AI link checks and device storage

When you press Check in AI Link Check, the URL you enter is sent to our server and the Lovable AI gateway, which uses an OpenAI model to analyze the URL text. This does not visit or verify the destination. Avoid submitting private links, password-reset links, access tokens or other sensitive information. AI results can be wrong.

Gallery images and uploaded logos are processed in your browser. Decoded text and generated QR images can be saved in history, including to Google Drive for Google accounts or Supabase for email accounts. Theme preferences, favorites and folders use device storage; authentication also uses browser storage to keep you signed in. Clearing browser data removes local records and preferences. Downloaded images and CSV exports remain on your device until you delete them.

Google advertising services may process IP addresses, device or advertising identifiers, cookies and ad interactions to deliver and measure advertising and prevent fraud, subject to applicable consent choices. Use the privacy settings provided by a consent message to review or withdraw your choices when available.

Notepad and note notifications

Notepad saves notes, list pins and the current draft in local storage on this device. Notes do not sync to your account. Clearing site or app data removes them; export important notes before doing so. In a supported browser or Android app, choosing Notify sends the selected note to your device's notification system after permission is granted. Notification previews may be visible to others using your device. A separate local pin record is saved; browsers also keep the notification preview in Cache Storage. Where supported, dismissed notifications return automatically until you choose Unpin notification in Notepad or History. Unpinning clears this record. Browser and device settings can block notifications, and a restart may clear them. The saved note remains until you delete it or clear device storage.

5. Log data

Like most websites, our hosting provider may automatically record basic technical information such as IP address, browser type and pages visited, for security and performance purposes.

6. Children's privacy

The app is not directed at children under 13 and we do not knowingly collect personal information from them.

7. Your rights

You can request access to, correction of, or deletion of your account and data at any time by contacting us.

8. Changes to this policy

We may update this policy occasionally. Changes will be posted on this page with a new date.
