Lin — Privacy Policy

Effective date: 16 July 2026 Last updated: 14 September 2026

This Privacy Policy explains how Lin ("Lin", "we", "us", or "our") collects, uses, shares, and protects personal information in connection with the Lin mobile application (the "App") and related services (together, the "Service").

Lin is a professional decision-support tool for permanent makeup (PMU) artists. It analyzes skin characteristics and suggests pigment matches and color-correction options. The App does not provide medical advice and does not replace professional training, examination, or judgment.

If you do not agree with this Policy, please do not use the Service.

1. Who we are (Data Controller)

The data controller responsible for your personal information is:

Lin HaAluf David St 17, Rishon LeZion, 7564041, Israel Email: linera.main@gmail.com

For questions about this Policy or your data, contact us at linera.main@gmail.com.

2. Important: professionals and their clients

Lin is used by PMU professionals ("you", the account holder). In the course of using the App you may enter information about your clients (for example, client face photos, a medical/intake questionnaire, and treatment records).

• For your own account data (name, email, phone, subscription), we act as the data controller.
• For the client data you enter, you are the controller and we act as your processor — we store and process that data on your behalf and under your instructions.

You are responsible for having a lawful basis and, where required, obtaining your clients' informed consent before entering their photos, health information, or other personal data into the App, and for providing your clients with any notices required by applicable law.

3. Information we collect

a. Account & professional information

• Name, email address, and phone number (phone is optional)
• Optional business name
• Authentication identifiers (including Sign in with Apple / Google identifiers, if you use them)
• A unique user ID

b. Client information you enter

• Client face photos (used to perform skin analysis)
• Health-related questionnaire responses (e.g. allergies, medications, pregnancy, skin conditions) that you choose to record
• Client records, notes, and diagnosis/analysis history

c. Analysis data

• Skin analysis results (e.g. tone, undertone, redness/couperose, pigmentation indications)
• Generated pigment-matching and color-correction recommendations

d. Subscription & purchase data

• Subscription status and purchase history
• Payments are processed by the Apple App Store or Google Play as in-app purchases; we do not collect or store your card details.

e. Diagnostics

• Crash reports and performance/diagnostic data used to keep the App stable

f. Data collected automatically

• Limited technical data necessary to operate the Service (e.g. app version, device/OS type) and product-analytics usage events that the App sends explicitly for specific actions (for example: an analysis was started or completed, a screen-level milestone, an error occurred). We do not use screen or touch autocapture, session recording, tracking or advertising identifiers, and we do not track you across other apps or websites.

We do not knowingly collect data for advertising, and we do not sell personal information.

4. How we use information

We use personal information to:

• Provide the core functionality of the App (skin analysis, pigment recommendations, client management)
• Create and manage your account and authenticate you
• Process and manage your subscription
• Provide customer support and respond to requests
• Maintain security, prevent fraud/abuse, and debug and improve the Service (diagnostics)
• Comply with legal obligations

Legal bases (GDPR/UK GDPR), where applicable: performance of a contract (providing the Service), your consent (e.g. processing photos and health-related data, optional fields), our legitimate interests (security, diagnostics, service improvement), and compliance with legal obligations.

5. Photos and AI analysis

When you request an analysis, a client photo is transmitted securely to our processing infrastructure and to our skin-analysis provider to generate results. The analysis is performed server-side; the resulting analysis data is stored in your account so you can review history. Photos are processed for the purpose of producing the analysis and are handled as described in this Policy. Recommendations are generated with the assistance of an AI/LLM provider based on the analysis outputs.

6. Health-related information

Some questionnaire fields (e.g. allergies, medications, pregnancy, skin conditions) and skin-analysis outputs may constitute health-related or special-category data. We process this data only to provide the App's functionality (to inform the analysis and recommendations) and never for advertising or profiling. Where the law requires explicit consent for such data, you (and, for client data, your clients via you) provide it by choosing to enter and submit this information.

7. Third parties / sub-processors

We share personal information only with service providers ("processors") that help us operate the Service, under contracts that require them to protect the data and use it only on our instructions. We do not sell personal information and do not share it for third-party advertising.

Please review each provider's privacy policy for details on their processing.

8. Sharing and disclosure

Beyond the processors above, we may disclose personal information:

• To comply with law, legal process, or lawful requests from public authorities
• To protect our rights, safety, and property, or those of our users or the public
• In connection with a merger, acquisition, or sale of assets, subject to this Policy

9. International data transfers

Your information may be processed and stored on servers located outside your country, including in jurisdictions that may have different data-protection laws. Where required, we rely on appropriate safeguards (such as the EU Standard Contractual Clauses) for such transfers.

10. Data retention

We retain personal information for as long as your account is active or as needed to provide the Service, and thereafter only as required to comply with legal obligations, resolve disputes, and enforce our agreements. When you delete your account, we delete or de-identify your personal data as described below, except where retention is legally required.

11. Security

We use technical and organizational measures to protect personal information, including encryption in transit (HTTPS/TLS) and access controls. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

12. Your rights and choices

Depending on your location, you may have the right to:

• Access the personal data we hold about you
• Correct inaccurate data
• Delete your data ("right to erasure")
• Port your data to another service
• Object to or restrict certain processing
• Withdraw consent at any time (without affecting prior processing)

You can exercise many of these rights directly in the App. To make other requests, contact linera.main@gmail.com. You also have the right to lodge a complaint with your local data-protection authority.

13. Account and data deletion

You can permanently delete your account and associated data from within the App: Profile → Delete Account. This removes your account and the data stored under it (including client records and photos), subject to any retention required by law. You may also email linera.main@gmail.com to request deletion.

Note: deleting your account removes data stored in the Service but does not by itself cancel an active subscription — cancel your subscription before deleting if one is active.

14. Children's privacy

The Service is a professional tool intended for use by adults (PMU professionals) and is not directed to children. We do not knowingly collect personal information from children. If you believe a child has provided us data, contact us and we will delete it.

15. Region-specific disclosures

• EEA / UK (GDPR): legal bases and rights are described in Sections 4 and 12.
• Israel (Protection of Privacy Law): you may access and request correction of your personal data as described above.
• California (CCPA/CPRA): we do not sell or "share" (as defined) personal information; California residents may exercise access and deletion rights as described above.

16. Changes to this Policy

We may update this Policy from time to time. We will revise the "Last updated" date and, where appropriate, notify you in the App. Your continued use of the Service after changes take effect constitutes acceptance of the updated Policy.

This document is a template prepared to reflect the App's actual data practices. It is not legal advice. Because the App handles health-related information, we strongly recommend having it reviewed by a qualified privacy/legal professional before publishing.
