Sync.me is a caller ID and spam-blocking app, and its website has a search box for any phone number. The site says a lookup can show the caller's name, location, photos and connected social profiles.
You don't have to use the app to be in it. Sync.me's privacy policy describes a "Name Tag" feature: once enough users have tied a phone number to the same name, that name and number go into its directory. Its opt-out is a short web form, and it doesn't need the app or an account.
Checked against Sync.me's live opt-out page, Do Not Sell page and privacy policy on October 19, 2026. We read the forms; we did not submit them, so we can't show what happens after you click Send.
Two footer links, one removal
Sync.me's footer has two links that open near-identical forms, each asking for a name, an email and a phone number:
- Opt-Out (sync.me/unsubscribe) opens a page headed Remove My Info, which says Sync.me will remove your information within 24 hours. This is the one that takes your number out.
- Do Not Sell My Info (sync.me/do-not-sell) asks for the same details but says nothing about removal or timing.
How to remove yourself from Sync.me
- Go to sync.me/unsubscribe.
- Enter your name, an email address and the phone number to remove. The country code starts at +1; use the picker for a number from another country.
- Leave "This request is submitted under Daniel's Law" unticked unless it applies to you (see below). The box is optional.
- Complete the security check and click Send.
The form takes one number at a time, so send it again for each number you want off: your mobile, old numbers, a landline.
How long does it take?
The Remove My Info page says within 24 hours. After a day, type your number into the search box on sync.me's home page and see what comes back. We didn't submit the form, so we can't say whether a confirmation email follows; take a screenshot before you click Send, and note the date.
What is the Daniel's Law box?
Daniel's Law is a New Jersey law. New Jersey's official Daniel's Law site says it stops government agencies, individuals and businesses from publishing the home address and phone number of covered people who ask for protection: active, former or retired judicial officers, prosecutors, law enforcement officers and Child Protective Investigators, plus immediate family members in the same household. Sync.me's form sums it up more briefly, as protecting private phone numbers. If you aren't covered, leave the box empty; the ordinary opt-out still applies.
Have a Sync.me account?
The opt-out form is about your number and the details tied to it. Closing your own account is a separate step: the privacy policy says you delete an account by emailing privacy@sync.me, and that public activity on the account before deletion stays on its servers and stays public. It also says information given to it, by you or by another user, is kept unless you tell Sync.me to delete it, so uninstalling the app is not a deletion request.
If it doesn't work
- Email privacy@sync.me. The privacy policy says you can ask for deletion there at any time, as well as through the opt-out page. Give your name and the number, and keep a copy of what you send.
- Expect identity questions. The policy says Sync.me may ask for more information to verify who you are before acting.
- Filing for someone else? The policy accepts an authorized agent who has written permission signed by the person.
Why your number can come back
Sync.me's directory isn't built only from what you tell it. The privacy policy says users who turn on its Sync.Me Search feature share the names, phone numbers and email addresses in their phone's contacts, and that the same information may also come from other users, from Sync.me's own collection or from public sources. It adds that using information from those other sources is not a breach of your rights, even after you ask to delete what you uploaded yourself. Anyone with you in their contacts can feed your number back in, so search it again every few months and file again if it reappears.

Who runs Sync.me. The site footer and privacy policy name Sync.me Solutions Inc.; the policy gives no postal address. Sync.me does not appear on California's data broker registry (searched October 19, 2026), so the state's DROP tool, which sends requests to registered brokers, is not a route here. File directly.

Frequently asked questions
Is the Sync.me opt-out free?
Yes. The form asks for no payment and no account.
Do I need the app to opt out?
No. The form at sync.me/unsubscribe works in a browser without the app or a sign-in. It does ask for an email address, so use one you check.
Is "Do Not Sell My Info" enough?
Not if you want your number out. That page asks for the same details as the opt-out but doesn't say it removes anything. Use Opt-Out (sync.me/unsubscribe), the page that states the 24-hour removal.
Your number lives in other people's contacts as well as on Sync.me. See which of the sites we track list it with a free Defynta scan.
