This notice explains the cookies, browser storage, pixels and server-side conversion tools used on the OnSync website and application. Essential technologies operate without optional consent. Analytics, advertising and affiliate measurement remain off unless you allow them.
Required to secure the service, maintain authentication, remember language and privacy choices, process billing, prevent abuse and provide requested features. These technologies cannot be disabled through the consent panel.
Google Analytics helps us understand page usage, funnel performance and technical performance. Google tags load only after analytics consent.
Google Ads, Meta Pixel and Conversions API, Snapchat Pixel and Conversions API, and Rewardful help attribute campaigns or referrals. These tools load or receive conversion events only after advertising consent.
Names and durations can change when providers update their services. We review this inventory when the consent version changes.

When advertising or analytics consent is granted, OnSync may send signup, checkout, trial or purchase events to the selected providers from our server. The consent version and choices are carried into Stripe metadata so later checkout webhooks fail closed when valid consent evidence is absent or expired.
Use the button below whenever you want to review or withdraw your choices. Rejecting optional technologies is as easy as accepting them. Withdrawal stops future optional browser tracking, removes known optional first-party identifiers where possible and prevents browser-triggered conversion API requests. Your browser can also delete existing provider cookies.
If your browser sends a Global Privacy Control signal, OnSync keeps advertising and affiliate measurement off. Analytics remains a separate choice.
