Do Not Sell or Share My Personal Information

Your right under California law

California residents have the right under the California Consumer Privacy Act (CCPA) and California Privacy Rights Act (CPRA) to direct Sincerus not to “sell” or “share” their personal information. Residents of Colorado, Connecticut, Virginia, Texas, Utah, and every other state with a comprehensive privacy law have substantially similar rights.

What Sincerus considers a “sale” or “share”

• Personalized Google ads on the free tier. Only if you allowed tracking in Apple's App Tracking Transparency prompt, Google's ad SDK in the app uses your device's advertising identifier and how you interact with ads to personalize Google ads. Do Not Sell or Share turns this off: Google ads become non-personalized, with restricted data processing, and Sincerus' own ads stop using your ad interests.
• Inclusion of your public posts in pseudonymized language corpora licensed to AI research partners. This is opt-in and off by default: your posts are included only if you turn on “Include my posts in anonymized corpora” in the app. Sincerus never licenses direct messages, profile information, posts by minors, or anything you have not posted publicly.

Those are the only activities that may count as a “sale” or “share.” Sincerus contains no analytics SDK, never gives advertisers who saw their ads (they get totals), and does not share data with data brokers. Premium members see no ads at all.

How to exercise this right

Open Sincerus on your device and go to Settings → Privacy Rights. Toggle “Do Not Sell or Share My Personal Information” on. Your request is honored immediately — you’ll see an “Opt-Out Request Honored” confirmation in the app. The switch turns off personalized ads and forces language-corpus licensing off, and every corpus export honors it. If you only want to withdraw from corpus licensing, turn off “Include my posts in anonymized corpora” on the same screen.

If you cannot use the in-app control, email privacy@sincerus.app with the subject line “Do Not Sell” and include the email address or username on your account. We verify the request and honor it within 15 business days (the CCPA maximum).

Authorized agents

California residents may designate an authorized agent to submit this request on their behalf. The agent must provide a signed written permission. Email the signed permission to privacy@sincerus.app along with the account identifier.

Non-discrimination

Sincerus will not deny you service, charge you different prices, or provide a lower quality of service because you exercised your privacy rights. The premium subscription, free DMs, and every other feature remain fully available whether or not you opt out.

Other privacy rights

You also have the right to know what we collect, to request a copy of your data (Download your data under Settings → Privacy Rights & Do Not Sell), to correct inaccurate data, and to delete your account (Settings → Delete Account). See our Privacy Policy for full details.
