Privacy Policy

Last updated: March 23, 2026

Overview

Lecto ("the App") is a photo mosaic and collage application developed by Koksoft ("we", "us", "our"). We are committed to protecting your privacy. This policy explains how we handle your data.

Data Collection & Analytics

Lecto uses Google Firebase to collect anonymous usage data and improve the app experience. This includes: crash reports and performance data (Firebase Crashlytics), anonymous usage events such as collage creation and feature usage (Firebase Analytics), and device information like device model and OS version. This data is anonymous and cannot be used to identify you personally. Your photos and personal content are never collected or uploaded.

Photo Library Access

Lecto requests access to your photo library to load photos that are used as tiles in your mosaics. Your photos are processed locally on your device and are never uploaded to any server. Photo access is managed through Apple's Photos framework and you can revoke access at any time through your device's Settings.

Push Notifications

Lecto uses Firebase Cloud Messaging to send push notifications. If you opt in, a device token is generated and stored by Firebase to deliver notifications. You can disable notifications at any time through your device's Settings. No personal information is collected through this service.

Data Storage

All app content (photos, collages, groups, preferences) is stored locally on your device. Anonymous analytics and crash data are processed by Google Firebase on their servers. We do not maintain our own servers or databases that store your personal data.

In-App Purchases

Lecto offers optional in-app purchases processed through Apple's App Store and managed by RevenueCat. Purchase status and anonymous user identifiers are stored by RevenueCat to manage your subscription. We do not have access to your payment information. All transactions are handled by Apple according to their privacy policy.

Third-Party Services

Lecto uses the following third-party services: Google Firebase (Analytics, Crashlytics, Cloud Messaging, Remote Config) and RevenueCat (subscription management). Each service has its own privacy policy. We encourage you to review them.

Children's Privacy

Lecto is not directed at children under 13. We do not knowingly collect data from children.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated revision date.
