Privacy Policy

1 Overview

FaceMap is developed and operated by Lilu Ram, doing business as DSLR Labs (“DSLR Labs”, “we”, “us”, or “our”).

FaceMap is a face-shape and facial-proportion analysis app. It measures your face using an on-device 468-point face mesh, classifies your face shape, computes a geometry-based "Face Score," and recommends hairstyles, beards, and glasses that suit your proportions.

This policy explains exactly what data the app touches, what it does with it, and what it deliberately never does (your photo and face data never leave your device) — it's written to match the app's actual behavior, not a generic template.

2 What FaceMap processes

Camera photo / picked photo

Used to detect your 468-point face mesh and compute measurements. Never leaves your device.

Face measurements & score

Used to classify your face shape and compute a symmetry/balance score and style recommendations. Never leaves your device.

A small cropped thumbnail

Shown in your scan History list. Never leaves your device.

Onboarding answers (age range, styling goals)

Used to personalize which styles are shown first. Never leaves your device.

Re-scan reminder preference

Used to schedule an optional local notification. Never leaves your device.

All five are computed and stored on your device only, using Android's local Room database and DataStore preferences. FaceMap has no server, no user database, and no way to see any of this even if it wanted to.

3 What we don't collect

• No name, email, or phone number — there is no account or sign-in system in FaceMap.
• No advertising identifiers, and no ad SDKs are built into the app.
• No photos, face measurements, scores, results, or anything you type are ever included in the anonymous usage counts described in section 7. FaceMap uses no crash-reporting SDK.
• No contacts, location, microphone, or broad photo-library access — FaceMap uses Android's system Photo Picker, which shares only the one image you explicitly select.
• No biometric identity data. Face mesh measurements describe geometry (proportions and distances), not an identity template, and are never used to identify or verify who you are.

4 Where your data lives

Everything FaceMap stores — scan history, thumbnails, measurements, and preferences — lives in a local database and local preferences file on your device. The app explicitly disables Android's automatic cloud backup and device-transfer for this data, so a scan's data doesn't silently follow you to a new phone or a cloud restore — uninstalling FaceMap removes it completely.

5 Permissions we ask for

Camera

To capture a photo for analysis. Only used while you're actively scanning.

Notifications

Only requested if you opt in to re-scan reminders — never asked for otherwise.

FaceMap does not request storage, contacts, location, or microphone permissions. FaceMap also has internet access, which is used only for purchases (Google Play and RevenueCat), anonymous usage counts (Firebase Analytics), and diagnostics from Google's on-device ML library. No photo, measurement, or face data is ever sent through it. See Third parties below.

6 Purchases & billing data

FaceMap offers an optional Premium unlock (₹149/week or a ₹499 one-time Lifetime option) via Google Play's Billing system, managed through RevenueCat. When you purchase, Google Play processes the transaction — FaceMap never sees or stores your card number, UPI ID, or any other payment credential. RevenueCat receives your purchase token and an anonymous device identifier so the app can check what you own; it never receives your photos, face measurements, or any other analysis data. Google's and RevenueCat's handling of this information is governed by their own privacy policies.

7 Third parties

Google ML Kit

Finds facial landmarks. The detection model is bundled inside the app itself at install time — it is not downloaded from Google at runtime — and runs entirely on-device. Your photo is processed locally by this library and is not uploaded to Google or any other server as part of that analysis.

Google Play Billing

Processes purchases of the optional Premium unlock. See "Purchases & billing data" above.

RevenueCat

Manages Premium entitlement state. Receives a purchase token and an anonymous device identifier only — never your photos or analysis data.

Firebase Analytics (Google)

Counts how the app is used so we can improve it. See "Anonymous usage counts" below.

Anonymous usage counts

FaceMap uses Firebase Analytics, a Google service, to count which screens and buttons are used. Examples: opened the camera, started or finished a scan, viewed the paywall, started a purchase, opened a style, shared a result.

• What is collected: these app-activity events, with fixed labels and rounded numbers (for example how many seconds a scan took, or which step of onboarding you reached), plus the app-instance ID that Firebase generates on your device, your app version, Android version, device model, approximate country, and language.
• What is never collected: your photo, face mesh, measurements, face shape, Face Score, results, anything you type, your name, email, or phone number, or your advertising ID. FaceMap does not use Firebase for advertising and does not share this data for ads.
• Your choice: turn it off any time in Settings → "Share anonymous usage". In the European Economic Area, the United Kingdom, and Switzerland it starts off and only begins if you turn it on. Turning it off stops new events from being sent.
• Retention: event data is kept in Firebase for up to 14 months and then deleted automatically. Data is processed by Google under its own privacy policy and may be handled on servers outside your country.

8 Your controls

• Delete a single scan: swipe or tap delete on any entry in History.
• Delete everything: Settings → Data & Privacy → Delete all my data — permanently removes every saved scan and photo immediately.
• Turn off usage counts: Settings → Share anonymous usage.
• Turn off reminders: Settings → Re-scan reminders, or revoke notification permission in Android's system settings.
• Uninstall: since nothing is backed up off-device, uninstalling the app removes all of the above along with it.

9 Children's privacy

FaceMap is intended for people aged 18 and over and is not directed at children, and we do not knowingly collect information from anyone under 18. The only data that leaves the device is the anonymous usage counts described above and purchase information handled by Google Play and RevenueCat, and none of it identifies a person by name or contains photos.

10 Changes to this policy

We will update this page when what FaceMap collects or how it's used changes, and note the date of the most recent revision above.
