This Privacy Policy describes how Waiver Sniper ("we", "us", or "our") handles data when you install and use the Waiver Sniper browser extension and visit waiversniper.com.
Waiver Sniper is built with a local-first privacy model. We do not collect, harvest, sell, or transmit your personal data, credentials, fantasy league details, or browsing history to any external servers. All automation logic and data processing occur entirely within your local browser.
Waiver Sniper operates locally on your machine and uses specific browser permissions strictly to perform its primary function: automating fantasy free agent claim submissions.
chrome.storage.local API.chrome.alarms to trigger claim processing at designated waiver clearance times.
The extension communicates directly with official endpoints of supported fantasy platforms (specifically sleeper.com and fantasysports.yahoo.com) to retrieve league data and submit transactions. These network requests are governed by the respective privacy policies of those platforms:
We do not sell, rent, trade, or transfer any user data to third parties under any circumstances. No user data is ever uploaded to external analytical services or remote databases managed by Waiver Sniper.
Because all data is stored strictly in your browser's local extension storage, you retain full control over it. You can clear your queued snipes at any time via the extension popup, or remove all associated local data instantly by uninstalling the extension.
We may update this Privacy Policy from time to time to reflect functional updates or regulatory requirements. Any modifications will be published directly on this page with an updated effective date.
