Privacy Policy

Last updated: April 24, 2026

Overview

Siftly is a photo management app that uses on-device AI to help you decide which photos to back up to Google Photos. We are committed to being transparent about how the app works and what data it touches.

What Siftly does

  • Reads photos stored on your device to classify them by category using on-device machine learning (ML Kit)
  • Connects to your Google Photos account to sync photos you choose to back up
  • Stores your sync preferences locally on your device

Data we collect

On-device data

All photo analysis happens entirely on your device. Your photos are never uploaded to any Siftly server — we do not operate one. Classification results and sync preferences are stored locally in the app's private storage.

Google account

When you connect Google Photos, Siftly requests permission to read and upload photos on your behalf via the Google Photos API. We only use this permission to carry out actions you explicitly request within the app. Your Google credentials are managed by Google and are never stored or transmitted by Siftly.

Crash reporting

Siftly uses Firebase Crashlytics, a service provided by Google, to collect crash reports so we can diagnose and fix stability issues. Crash reports include technical information such as your device model, operating system version, a Firebase-generated installation identifier, approximate region derived from your IP address, and the stack trace of the crash. Crash reports do not include your photos. Crash reporting is enabled only in release builds of the app. You can review Google's privacy practices at firebase.google.com.

Data we do not collect

  • We do not collect your name, email address, or any personal information beyond what Google provides for authentication
  • We do not sell, rent, or share your data with third parties
  • We do not have access to your photos outside of what is needed to perform sync actions you initiate
  • We do not store any data on external servers

Third-party services

Siftly integrates with the following third-party services:

  • Google Photos API — to read and upload your photos. Subject to Google's Privacy Policy.
  • Firebase Crashlytics (Google) — for crash reporting. Subject to Google's Privacy Policy.

Data retention

All local data (preferences, classification results) is deleted when you uninstall the app. Siftly does not retain any data after uninstallation.

Your rights

You may revoke Siftly's access to your Google Photos account at any time via your Google Account permissions page. You may also delete all local app data by uninstalling Siftly.

Children's privacy

Siftly is intended for users aged 18 and older. We do not knowingly collect data from children under 13.

Changes to this policy

We may update this policy from time to time. The "Last updated" date at the top of this page will reflect any changes. Continued use of the app after changes constitutes acceptance of the updated policy.
