Siftr — Privacy Policy

Effective date: June 12, 2026

Siftr is a Chrome extension that turns Gmail inbox triage into a card game. This policy explains exactly what data Siftr accesses, what it stores, and what it transmits. The short version: your emails never leave your device.

What Siftr reads

To build the card deck, Siftr reads the Gmail inbox rows already visible in your browser tab: sender name, subject line, preview snippet, date, read/unread state, and Gmail's internal thread ID. This happens entirely inside your browser. Siftr does not use the Gmail API, does not request access to your Google account, and cannot read email bodies beyond the preview snippet Gmail itself displays.

What Siftr stores — locally only

• Game progress: points, streaks, ranks, session stats.
• Reviewed threads: Gmail thread IDs you have already swiped, so the same email is not shown twice.
• License status: your Pro license key and its last validation date, if you purchased Pro.

All of this is kept in Chrome's local extension storage (chrome.storage.local) on your device. It is not synced, uploaded, or shared. Uninstalling the extension deletes it.

What Siftr transmits

Exactly one piece of data ever leaves your device: your license key, sent to Polar.sh (api.polar.sh) when you activate Pro and periodically afterwards (at most once per week) to confirm the license is still valid. No email content, no metadata, no usage statistics are included in these requests. Polar.sh processes payments and licensing under its own privacy policy.

What Siftr does not do

• No analytics, telemetry, or tracking of any kind.
• No email content is collected, transmitted, stored remotely, or sold.
• No third-party scripts, ads, or remote code.
• No data is sold or shared with anyone, for any purpose.

Deleting emails

When you swipe an email to trash, Siftr clicks Gmail's own delete button in the page. Deletion is performed by Gmail itself, follows Gmail's normal behavior (items go to Trash and can be restored), and can be undone with Gmail's "Undo" — which Siftr also exposes as a button.

Limited Use disclosure

Siftr's use of information received from Google services adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. Gmail data is used solely to provide the user-facing triage feature, in your browser, and for no other purpose.

Changes & contact

If this policy changes, the new version will be published at this address with an updated effective date. Questions: hey@ardakaanozcan.com
