To stop an app from accessing Google Account data, open your account's connections page, select the service and inspect its permissions before removing access. That list also includes services that use Google simply to identify you at sign-in. Read the connection details so you change the right setting.
This guide was checked on September 7, 2026. Use it for a privacy review on Android or a computer after trying new tools, abandoning an app or encountering a request for more access than you expected.
Remove an app's permission
- Open your Google Account connections in a trusted browser.
- Check the email address in your profile. Review personal and work accounts separately.
- Find the account-access filter and select the app.
- Open its details and read which products and information it can access.
- Choose the option to remove access and confirm.
- Return to the list and verify that authorization was removed. Review any other connection types for the service separately.
Interface labels can vary. Google's connection management instructions distinguish data access, sign-in and linked accounts. Pay attention to the connection type when making a change.
Understand the three connection types
Sign in with Google: identifies you to the service using the authorized basic profile, such as your name, email and picture. It does not share your Google password or, by itself, grant access to Gmail messages. Google's sign-in privacy explanation describes that distinction.
Access to account data: the app received additional permissions. Depending on the authorization, it may be able to read, copy or change information. Read the actual scope on screen instead of judging by a familiar app name. See Google's guide to sharing partial account access.
Linked account: can let Google use features of another service, such as a music integration. Check which way information flows before deciding what to disconnect.
Preserve access to services you still need
Our editorial suggestion for routine cleanup is to start with a service you have stopped using. For an important app, note its registered email and look in that app's settings for an alternative sign-in method. If available, set it up and test it before removing Google sign-in. Avoid signing out of your only working session just to run a test.
For example, imagine a task organizer you use every week that also has an old calendar integration. First identify the calendar permission. Removing the sign-in connection as well could create unnecessary trouble if you have no alternative. Contact the organizer's support if the effect of its disconnect button is unclear.
Prepare your main account by updating your recovery phone and email. That is separate from retaining access to the third-party app, but it helps you avoid doing account maintenance when you are already locked out.
Decide what to review first
Ask three questions: do I still use this service, do I recognize its operator, and can I explain why it needs this information? Start with forgotten trials, abandoned tools and access unrelated to the task you want. Broad permissions deserve a clear reason rather than an automatic removal without checking the impact.
A connected app is also different from a signed-in phone. To inspect device sessions, follow our Google Account device review. For activity you do not recognize, use the sign-in alert checklist. Permission cleanup alone does not address every type of account compromise.
Does removing access delete my data?
It does not erase information the service already received. Revocation stops the corresponding access; deleting stored copies requires dealing with the app directly. Removing a sign-in connection also does not delete the account you created with that service, as Google's privacy documentation explains.
After your review, open the apps you kept and check whether the features you need still work. Read any new consent request carefully. Approving it automatically could restore the access you intended to remove.
Finish with a short checklist
- Check which Google Account is open.
- Distinguish sign-in, account linking and data permissions.
- Preserve a working sign-in method for services you still use.
- Verify the result of each removal.
- Handle data deletion separately from access revocation.
Complete your sign-in protection with a Google Account passkey. It complements permission reviews by protecting a different part of your account security.
