LineMax Privacy Policy

Effective date: October 6, 2026 Last updated: October 6, 2026

This Privacy Policy explains what information the LineMax mobile app (the "App") collects, why, who it is shared with, and the choices you have. LineMax is operated by Dinesh R, an individual developer based in India ("LineMax", "we", "us"). We are responsible for your personal data as described here.

The short version:

• LineMax works without an account. Unless you turn on cloud backup, your photos stay on your device and never reach us.
• If you turn on cloud backup, your photos are stored in private, access-controlled storage that only your account can read.
• We have no advertising, no analytics trackers, and no data selling.
• Your treatment log never leaves your device.
• You can delete your account and cloud data from inside the App at any time.

1. Information that stays on your device

When you use LineMax, the following is created and stored only on your device unless you turn on cloud backup:

• the photos you take (front, left temple, right temple, crown);
• scan details such as capture time, photo position, and which scan is your baseline;
• your app settings and preferences;
• your treatment log (for example, routines or products you choose to note down). The treatment log is never uploaded to our servers, even with cloud backup turned on.

We cannot see or access information that stays on your device.

2. Information we collect

a) If you create an account (optional)

• Email address and password. Used to sign you in. Passwords are handled by our authentication provider and stored in hashed form. We never see your password.
• Account identifiers. An internal user ID, the date your account was created, when you finished onboarding, and a referral code generated for you.

b) If you turn on cloud backup (optional)

• Your scan photos. These are photos of your head, hairline, and face area.
• Scan details. Capture time, photo position, whether the photo was mirrored, image dimensions, sync status, whether the scan is your baseline, and the tracking focus you selected.

c) If you buy LineMax Pro

• Payment details are handled entirely by Apple or Google. We never receive your card number or billing details.
• We receive subscription status from our subscription provider: which plan you have, whether it is active, whether it will renew, its expiry date, and a log of subscription events (event type, event ID, timestamp, and your app user ID).

d) If you use referrals

• If you invite someone or join through a referral, we record the link between the two accounts, when the referral qualified, and any reward granted.

e) Contacting us

• If you email us, we receive your email address and whatever you write.

3. Information we do NOT collect

• No advertising or analytics SDKs. We do not track you across apps or websites.
• No face recognition or facial analysis. We do not extract facial landmarks, face meshes, or biometric identifiers from your photos, and we do not use your photos to identify you.
• No location, contacts, or microphone data.
• Motion sensor data (used to help you hold your phone level while taking photos) is processed on your device only and is not uploaded.
• No treatment log data on our servers (see Section 1).

4. How we use information

We use information only to:

• provide the App's features, such as capture, comparison, history, and cloud backup and restore;
• sign you in and keep your account secure;
• unlock and verify LineMax Pro, and prevent subscription fraud or abuse;
• run the referral program;
• respond to your support requests;
• meet legal obligations.

We do not use your photos for advertising, marketing, profiling, or training AI models, and we do not sell or rent your personal data.

5. Legal bases (where applicable)

Where data protection laws such as India's Digital Personal Data Protection Act, 2023, or the EU/UK GDPR apply, we process your data:

• with your consent. Cloud backup and creating an account are optional and you choose to turn them on. You can withdraw consent at any time by turning off backup or deleting your account;
• to perform our contract with you. This covers providing the App and any subscription you purchase;
• for legitimate interests. This covers security and fraud prevention;
• to comply with legal obligations.

6. Who we share information with

We share information only with service providers that help run the App, and only as needed:

We may also disclose information if required by law, to protect the rights and safety of users or others, or as part of a sale or transfer of the App. In that case this Policy, or one at least as protective, will continue to apply.

7. International transfers

Our service providers may store or process data in countries other than where you live, including outside India. When that happens, we rely on the providers' contractual and security safeguards to protect your data.

8. How long we keep information

• Data on your device: until you delete it or uninstall the App.
• Account and cloud data: until you delete your account. When you delete your account in the App, we delete your backed-up photos from storage, confirm they are removed, and then delete your account and its linked records (scans, subscription status, and referral records).
• Subscription event log: minimal records (event ID, event type, app user ID, and timestamp) are kept after account deletion to prevent duplicate or fraudulent subscription events and for accounting purposes. They contain no photos or contact details.
• Apple, Google, and RevenueCat keep their own purchase records under their own policies.
• Support emails: for as long as needed to resolve your request, and then deleted within a reasonable period.

9. How we protect your information

• All data sent between the App and our servers is encrypted in transit (HTTPS).
• Backed-up photos are stored in private storage. Database rules restrict every record so that only your account can access your own data.
• Your sign-in session is stored in your device's secure storage (iOS Keychain or Android Keystore).
• Subscription status can only be changed by our server, never by the App.

No system is perfectly secure. If a data breach affects your personal data, we will notify you and the relevant authorities as required by law.

10. Your choices and rights

You can:

• use LineMax without an account;
• turn cloud backup on or off;
• delete your account and cloud data in the App: Profile → Cloud Backup → Delete Account. Or request deletion at the account deletion page;
• access, correct, or get a copy of your personal data, or withdraw consent, by emailing support@linemax.online;
• complain to a data protection authority. In India this is the Data Protection Board of India; if you are in the EU or UK, it is your local supervisory authority.

We will respond to requests within the time required by applicable law, and in any case within 30 days where possible. We may need to verify your identity first, for example by asking you to email us from your account's email address.

Deleting the App does not delete your cloud data or cancel your subscription. Manage subscriptions in your App Store or Google Play settings.

11. Children

LineMax is intended for users 18 and older. We do not knowingly collect personal data from anyone under 18. If you believe a minor has created an account or uploaded photos, contact us at support@linemax.online and we will delete it.

12. Changes to this Policy

We may update this Policy. If we make material changes, we will notify you in the App or by other reasonable means before they take effect. The "Last updated" date above shows the latest version.
