What Google is actually saving (and where)
When you email someone new, Google may quietly add their address to a list called Other contacts. This is not the same as your manually created contacts. It is a record built from your interactions across Google services.

That distinction matters because many people assume their contact list only contains people they deliberately saved. In reality, Google may keep a parallel list of addresses and phone numbers it has seen you interact with. The setting that controls this behavior lives in your Google Account, not inside the Gmail compose window.

Gmail’s auto-complete feature is related but separate. Even if you stop Google from saving new interaction-based contacts, Gmail may still offer suggestions from your existing contacts and Other contacts. The auto-complete setting controls what appears as you type, not whether new interaction-based entries are created.
Step 1: Stop new automatic entries at the account level
The first step is to find the account-level control for contact info saved from interactions. The exact menu labels can change, so navigate by concept rather than memorized clicks: look for People & sharing in your Google Account settings, then find the section about contact info saved from interactions. Turning this off should prevent new automatic entries from being created from your future interactions. This is the only reliable way to stop the behavior at its source. Changing Gmail’s auto-complete settings alone will not stop new entries from being saved.
Step 2: Adjust Gmail’s auto-complete separately
Gmail has its own setting for creating contacts for auto-complete. This controls whether Gmail automatically creates contacts as you email new addresses. It is a separate choice from the account-level interaction-saving control. You may want to turn this off as well if you do not want Gmail building contacts from your sent mail. However, this setting does not remove entries that already exist in Other contacts. Treat it as a complementary control, not a replacement for Step 1.
Step 3: Review and clean up existing Other contacts
Stopping new saves does not erase what is already there. You need to review the existing Other contacts list and decide what to keep. The list may contain people you emailed once, automated addresses, or old colleagues. You can edit or delete individual entries.

A common point of confusion: hiding a suggestion is not the same as deleting the contact. If you only hide an auto-complete suggestion, the underlying contact record may remain. To actually remove an entry, you need to delete it from the Other contacts list. The table below summarizes the difference between the main actions.
| Action | What it affects | Does it delete the contact? |
|---|---|---|
| Turn off contact info saved from interactions | Future automatic saving from interactions | No — existing entries remain |
| Turn off Gmail’s create contacts for auto-complete | Whether Gmail creates contacts from sent mail | No — existing entries remain |
| Hide an auto-complete suggestion | What appears as you type | Not necessarily — the contact may still exist |
| Delete an Other contact | The specific contact record | Yes — for that entry |
Common mistakes
- Assuming Gmail’s auto-complete setting stops all saving. Gmail’s setting is separate from the account-level interaction-saving control. You may need to adjust both.
- Hiding instead of deleting. Hiding a suggestion does not delete the contact. If your goal is removal, delete the entry from Other contacts.
- Expecting old entries to disappear automatically. Turning off saving affects future behavior only. Existing Other contacts stay until you edit or delete them.
- Confusing Other contacts with your main contacts. Other contacts are a separate list. Deleting from one may not affect the other, so review both if you are doing a cleanup.
- Treating a username match as proof of ownership. If you use a username search to check your own public footprint, remember that public matches are leads, not proof that an account belongs to you or anyone else.
Owner-side review checklist
Use this checklist to take control of your contact data without breaking anything you rely on.
- Locate the account-level setting for contact info saved from interactions and turn it off.
- Locate Gmail’s create contacts for auto-complete setting and decide whether to turn it off.
- Open the Other contacts list and scan for entries you did not intentionally save.
- For each unwanted entry, choose delete rather than hide if you want it removed.
- For entries you want to keep, consider editing them or moving them to your main contacts.
- Re-check the list after a few weeks to confirm no new unwanted entries are appearing.
- If you use a username search tool like TraceSeek to review your own public handles, treat the results as a starting point for your own verification, not as a privacy control. TraceSeek checks 3,000+ platforms and offers a free first scan; it does not change Google settings or access private content.
Limits: what these steps cannot do
These controls affect Google’s saving of interaction-based contact info and Gmail’s auto-complete behavior. They do not remove your email address from other people’s contact lists, from recipients’ inboxes, or from third-party services. They also do not delete emails you have already sent. If you are trying to trace where your email address appears online, see our guide on finding accounts by email address. For a broader approach to forgotten accounts, our guide on finding forgotten online accounts may help. But be clear about scope: stopping Google from saving new contacts is a narrow privacy fix, not a full erasure of your digital footprint.
Protecting your own footprint
Automatic contact saving is one small piece of a larger picture. Your email address and username can appear in many places you have forgotten. A practical approach is to periodically review the lists that services build about you, starting with the ones you use daily. Google’s Other contacts is a good example because it is easy to overlook. Once you have stopped new automatic entries and cleaned up old ones, consider doing the same review for other services that offer similar interaction-based saving. Keep a simple record of what you changed and when, so you can verify later that the settings held. And when you check your public presence, remember that a username search is a lead-generation tool, not a verification service. Use it to find candidates, then confirm each one yourself.
