Snapchat
What the default settings do
Snapchat’s account-level defaults are fairly conservative: only added friends can contact you or view your Story, and Snap Map location sharing is off by default until you turn it on. Snapchat’s help center doesn’t describe a different Snap Map default for teen versus adult accounts, though other defaults, like who can message you, are stricter for accounts registered as under 18.
Snapchat has no “last seen” or typing indicator like Instagram or WhatsApp. Instead, each Snap or Chat shows the recipient a “Delivered” then “Opened” status once viewed, and this can’t be turned off. Separately, an optional “Activity Indicator” shows friends when you’re currently in the app; unlike delivery status, this one can be disabled.
My AI, Snapchat’s built-in chatbot, sits in the chat feed for all users and retains what you send it, including one-on-one chats and any @-mention, until you delete it, unlike ordinary Snaps and Chats which are typically removed after viewing. Contact syncing and ad personalization use dedicated toggles in Settings, and Memories (saved Snaps and Stories) can back up to Snapchat’s servers automatically. Since late 2025, free Memories storage has been capped at 5GB, with paid plans for more; Snap promised 12 months of temporary storage for anything over the cap so people have time to upgrade or download it.
Ads are also moving into Chat. Snapchat already places Sponsored Snaps in the Chat tab, and in April 2026 it announced AI Sponsored Snaps, ads in that same tab where you can type questions to a brand’s AI agent and get answers and recommendations. Anything you write there goes to an advertiser’s chatbot, not to a friend.
A reasonable privacy baseline
These settings are found in Settings within the Snapchat app (tap the gear icon from your profile), unless noted otherwise.
Account security
Two-Factor Authentication → On, using an authenticator app (Settings → Two-Factor Authentication, under My Account)
Two-factor authentication means a stolen password alone is not enough to get into your account. Snapchat recommends an authenticator app such as Google Authenticator, Duo, Microsoft Authenticator, or a password manager over text message codes, which can be intercepted if your phone number is hijacked. Snapchat also supports adding a passkey, which lets you sign in with your phone's fingerprint, face, or PIN. Save your recovery code, since resetting your phone or deleting the authenticator app without it can lock you out.
Location and Snap Map
See My Location → Ghost Mode → On (Settings → My Privacy & Data → See My Location, or the gear icon on the Map)
Location sharing is off by default for anyone who has never opened Snap Map, functionally the same as Ghost Mode. If you've ever turned Snap Map on, confirming Ghost Mode is enabled hides your location from everyone on the Map. Snapchat still receives your location in the background with Ghost Mode on; it just isn't shown to other Snapchatters.
Location sharing list → Share with a small, chosen group rather than All Friends (Map settings)
If you do share your location, Snapchat lets you pick specific friends rather than everyone on your list. Keeping this list small limits who can track your movements; a separate "Live Location" share with an individual friend can still show on the Map even with Ghost Mode otherwise on.
Activity Indicator → Off (Settings → My Privacy & Data → Activity Indicator)
This is Snapchat's equivalent of an "active now" status, a marker showing friends you're currently in the app. Turning it off does not affect the "Delivered" and "Opened" status on individual Snaps and Chats, which cannot be disabled.
My AI
Delete My AI Data → Run periodically (Settings → Privacy Controls → Delete Data → Delete My AI Data on iOS; Settings → Account Actions → Delete My AI Data on Android)
This clears what you've sent to or discussed with My AI. Snapchat's help pages state it can take up to 30 days to fully clear from its servers. The last 24 hours of a specific message can also be removed by long-pressing it in the chat and selecting delete.
Unpin or Clear My AI from Chat Feed → Your preference (press and hold "My AI")
You can unpin My AI so it no longer sits at the top of your feed, or clear the thread. Neither deletes previously shared data; use Delete My AI Data for that. Snapchat's pages describe unpinning and clearing as available to everyone, but don't say whether fully removing My AI from the feed requires Snapchat+. Third-party guides claim it does; we couldn't confirm this on Snapchat's own help pages, so treat it as likely but unverified.
Contacts and Find Friends
Contact Syncing → Sync Contacts → Off (Settings → Privacy Controls → Contact Syncing)
When enabled, Snapchat uploads your phone's contact list to suggest friends and power "Find Friends" (formerly called Quick Add). Turning this off stops new uploads; review what's already shared under Settings → Contacts → See Contacts Shared with Snapchat.
Find Friends visibility → Off or limited (Settings → My Privacy & Data → Find Friends)
This controls whether you appear in others' friend suggestions, which can be driven by mutual friends or by uploaded contacts. Snapchat notes changes here can take up to 72 hours to take effect.
Ads and data
Ad Preferences → Turn off Audience-Based, Activity-Based, and Third-Party Ad Networks (Settings → App & Privacy → Ads → Ad Preferences)
These toggles control whether ads use advertiser audience lists, your activity across Snapchat and partner sites, and third-party ad network data. Turning them off means ads won't be tied to those sources; Snapchat notes users in the EEA, UK, and Switzerland aged 13-17 already have some of these restrictions by default.
Ad Topics and Lifestyle Categories → Review and adjust (same Ads menu)
You can hide sensitive ad topics, such as alcohol, gambling, or political ads, and review or remove the "lifestyle category" inferences Snapchat has made about your interests.
Sponsored Snaps and AI Sponsored Snaps in Chat → Treat as ads; share nothing personal
These ads appear in the same list as your conversations with friends. When an ad invites you to chat with a brand's AI agent, remember that your questions go to that advertiser's system, so avoid sharing personal details there the way you might in a chat with a friend.
Memories
Smart Backup → Your preference (Settings → Memories → Smart Backup)
When on, Memories back up automatically to Snapchat's servers, including over mobile data if Wi-Fi isn't available. Snapchat's documentation doesn't describe standard Memories storage as end-to-end encrypted, so treat it as accessible to Snapchat like most cloud storage, unlike the stronger protection described for My Eyes Only below.
Memories storage → Check your usage and download what you want to keep (Settings → Memories)
Free Memories storage is now limited to 5GB. If you are over it, Snapchat will prompt you to buy a storage plan, and Memories beyond the cap are only kept temporarily. Downloading your Memories to your own device or a backup you control is free, keeps them available whatever happens to your plan, and reduces how much of your photo history sits on Snapchat's servers.
My Eyes Only → Use for sensitive saved content (within Memories, set a separate password)
This is a password-protected, encrypted section of Memories that Snapchat says it cannot access even if your account is compromised. If you forget this separate password, though, Snapchat has no way to recover the content inside it.
Trade-offs
- Keeping Ghost Mode on means friends can’t see your location, even when briefly sharing it would be convenient, like meeting up somewhere new.
- Turning off the Activity Indicator has no reciprocal loss; you simply stop broadcasting when you’re active.
- Deleting My AI data regularly means losing any continuity it had from prior conversations.
- Turning off contact syncing and Find Friends visibility may make it harder for people you know to find you, especially without a shared username.
- Turning off ad personalization means less targeted ads, not fewer ads overall.
- Turning off Smart Backup risks losing device-only Memories permanently if you lose or replace your phone without exporting them first.
- Two-factor authentication adds a step when you sign in on a new device, and an authenticator app means keeping your recovery code safe.
- Downloading Memories to manage the 5GB cap means looking after that copy yourself, and a paid plan is the only way to keep a large archive inside Snapchat.
- My Eyes Only adds a password you’re solely responsible for, with no recovery if it’s forgotten.
Who should not change these settings
- If you use Snap Map to coordinate with a specific group, sharing your location with that group may be more useful than full Ghost Mode.
- If you rely on Find Friends and contact syncing to connect with people you know, especially without a shared username, leaving these on may be worth it.
- If you use My AI regularly and value it remembering context, there’s no need to clear its data on a strict schedule.
- If you’re comfortable with Snapchat’s ad practices and prefer more relevant ads, leaving personalization on is a preference, not a security issue.
- If your Memories are well under 5GB, there is nothing to do about the storage cap.
- If you find it useful to ask a brand’s AI agent about a product, there is no harm in doing so, as long as you keep personal details out of the conversation.
- If you don’t save anything sensitive to Memories, standard backup without My Eyes Only is a reasonable, lower-friction choice.
