Privacy Policy

Last Updated: April 26, 2026

Effective Date: April 26, 2026

1. Introduction

Welcome to Hairli. This Privacy Policy explains how Yusuf Şahan Tarhan ("we," "us," or "our") collects, uses, shares, and protects your information when you use the Hairli mobile application (the "App"). Hairli is an AI-powered tool that lets you preview different hairstyles and hair colors on your own photo.

We are committed to minimizing data collection and being transparent about what we do with the limited information we handle. By using Hairli, you agree to this Privacy Policy.

Operator Information:

2. Information We Collect

2.1 Anonymous Account Identifier

Hairli does not require you to create an account, sign up with email, or provide your name, phone number, or any other personal identifier. When you first launch the App, we generate a random anonymous identifier (a UUID) so that we can track your remaining credits and subscription status. This identifier is not linked to your real-world identity.

2.2 Photos You Provide

To generate a hairstyle preview, you choose a photo from your photo library or take a new one with the camera. The photo is sent to our processing service to be transformed by the AI model. Photos typically contain your face, since the App is designed to apply new hairstyles to a person in the image.

We do not store your photos on our servers. Photos are transmitted only to perform the requested transformation and are not retained, logged, or saved to any database after the AI response is returned to your device. The original photo and the generated result remain on your device unless you choose to share or save them yourself.

2.3 Style Selections

Each generation request includes the haircut style and hair color you selected (e.g. "Bob", "Platinum Blonde"). These selections are sent to the AI model along with your photo, but they are not associated with your identifier in any persistent record.

2.4 Subscription and Credit Data

We maintain a small record tied to your anonymous identifier with the following fields:

We do not directly collect or store any payment card information. All purchases are processed by Apple's App Store and managed by RevenueCat. We only receive a confirmation that a purchase or subscription event occurred for your anonymous identifier.

2.5 Locally Stored Data

The following items are stored only on your device and are never transmitted to us:

2.6 Information We Do Not Collect

3. Face Data Handling

Because Hairli is built around photos of people, the photos you upload typically contain your face. Apple requires us to clearly explain how this kind of data is handled. Please read this section carefully.

3.1 What "Face Data" Means in Hairli

Hairli does not perform facial recognition, identity verification, biometric identification, or face-based authentication. We do not build a faceprint, face template, or any mathematical representation of your face. We do not match your face against any database. We do not attempt to identify who you are from your photo.

The only thing the AI does with your photo is generate a new image where the hair has been visually modified. The AI model needs to look at the photo as a whole image (including the face) in order to produce a realistic result, but it is not used as a biometric identifier.

3.2 What We Do With Your Photos

3.3 Your Control

You choose every photo you upload. You can revoke camera or photo library access at any time in your device's iOS settings. You are not required to upload a photo of yourself — the App will work with any photo you choose, although results may vary.

4. How We Use Information

We do not use your information for advertising, profiling, or any purpose other than operating the App.

5. Third-Party Service Providers

We rely on a small set of service providers to run the App. They process information only on our behalf and only for the purposes described below.

5.1 AI Processing — Google Cloud and fal.ai

Photo transformation is performed by AI image models running on Google Cloud and/or fal.ai. These providers process your submitted photo and style selections only to generate the requested hairstyle preview. Per Google Cloud's published terms, customer inputs to its enterprise AI services are not used to train Google's foundation models, and inputs are not retained beyond what is necessary to provide the service. See Google Cloud's privacy notice and fal.ai's privacy policy.

5.2 Apple App Store

All purchases are processed by Apple. Apple receives the information necessary to complete the transaction. We do not receive your payment details. See Apple's privacy policy.

5.3 RevenueCat

RevenueCat manages our subscription entitlements. It receives your anonymous user identifier and purchase events from Apple, and notifies our backend when your subscription status changes. See RevenueCat's privacy policy.

5.4 Backend Infrastructure

Our backend (authentication, database, and request routing) runs on standard cloud-hosting providers under industry-standard data-protection agreements. These providers process limited operational data (such as your anonymous identifier and connection metadata) solely to deliver the App's functionality. They do not use your data for any independent purpose.

6. Data Retention

7. Data Sharing and Disclosure

We do not sell your information. We do not share it with advertisers. We do not share it with any third party other than the service providers listed in Section 5, who process it strictly to operate the App on our behalf.

We may disclose information if required to do so by law, by valid legal process, or to protect against fraud, abuse, or threats to the security of the App.

8. Your Rights

Depending on where you live, you may have the following rights regarding your information:

Because Hairli does not collect your name or email, we may need additional information (such as your anonymous user identifier, which can be found in the App's settings) to locate your record before acting on a request. To exercise any of these rights, email [email protected].

9. Security

All network traffic between the App and our backend is encrypted via HTTPS/TLS. Authentication tokens are stored on your device using the platform's secure storage. We rely on the security practices of Apple, Supabase, Cloudflare, Google Cloud, fal.ai, and RevenueCat for data they handle on our behalf. No method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

10. Children's Privacy

The App has an Apple App Store age rating of 9+. However, because Hairli processes photos of people (including faces), we ask that the App not be used by children under 13. Children between 9 and 13 should only use Hairli with the involvement and consent of a parent or legal guardian. We do not knowingly collect information from children under 13. If you believe a child under 13 has used the App, please contact us and we will delete any associated record.

11. International Data Transfers

The App is operated from Turkey, and our service providers operate globally. By using the App, you acknowledge that your information may be processed in countries other than your own, including the United States and the European Union. Where required, transfers are protected by appropriate safeguards offered by the relevant service providers (such as standard contractual clauses).

12. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last Updated" date at the top of this page. Material changes will be highlighted in the App or on this page. Your continued use of the App after a change takes effect means you accept the updated policy.
