OneContact is a smarter way to manage your contacts. You connect once, and when someone updates their info (phone, email, address, name), it updates automatically for the people they’ve chosen to share it with. 

No more outdated numbers. No awkward “is this still your email?” texts. Just always-up-to-date contact info—without the hassle.

You can download OneContact from the App Store or Google Play. Use the link below to get the correct version for your device:

The more people you’re connected with on OneContact, the more reliable your contacts become. Invite friends, family, and colleagues so updates stay accurate and automatic across your network.

We share short tutorials and walkthroughs on our YouTube channel to help you get the most out of OneContact.

To link your social media accounts in OneContact, you’ll need to enter the username or handle you use on each platform (not the full URL).

Your handle is the unique name people use to find you, usually shown with an @.

If you’re not sure where to find it, use the official resources below. These pages are maintained by each platform, so they’ll stay accurate even if layouts change.

Note: Some of the resources below explain how to change your username. You do not need to change anything — these pages also show you where to find your current username or handle, which is all you need for OneContact.

Yes. OneContact works through mutual connections so updates are intentional, private, and controlled.

Whatever you choose: phone number, email, address, birthday, profile photo, and more.

Your changes instantly sync to the people you’re connected with—no texts, emails, or reminders needed.

Personal Notes let you add private reminders to fully connected contacts. These notes are only visible to you—your connection will never see them. You can use Personal Notes to remember details like relationships, context, or helpful reminders (for example, “Jim’s sister” or “Rec League Softball Coach”).

No. Personal Notes are for your reference only and are never shared. Since OneContact is designed for contacts to keep their own information up to date, Personal Notes help you remember details about that person when you need a reminder.

We share feature updates, improvements, and important announcements through the app and on our official social media channels. You can find all of our social links here:

Neither. It’s not social, and it’s not a static card. It’s a living contact that stays accurate.

Each contact has a colored ring that shows the status of your connection:

• A glowing circle indicates the card you’re currently sharing with that contact

• A gray circle means you’re not connected

This makes it easy to see who you’re connected with and what you’re sharing at a glance.

This means the connection was removed by you or the other person. You can send a new request by tapping Reconnect.

Check your device settings to make sure notifications are enabled for OneContact. If notifications are off, connection requests may still appear in the app but won’t trigger an alert.

This usually means one of the password requirements is missing. Double-check that your password is at least 8 characters, includes upper and lowercase letters, a number, and a special character.

If you’re signed in, go to Settings and tap Change Password. If you can’t log in, open the app, tap Already have an account, then select Forgot Password and follow the prompts.

You can contact us directly in the app by tapping Contact Us and filling out the form.

You can also email us at onecontact-contactus@behappyinnovations.com 

OneContact uses live connections, so updates sync automatically. If something looks out of date, close and reopen the app and make sure you have an internet connection.

Edit the card you shared with that connection. Any changes to that card will update for everyone you’ve shared it with.

They control what they share. Not all fields are visible to every connection.

Phone sync can be turned on or off anytime from the Sync to Device section in app.

OneContact creates its own contacts group on your phone. If you already saved the same person from another source, both may appear when viewing all contacts together. OneContact contacts can’t be merged with existing contacts, so you can choose to keep or delete the other entry if needed.

Check spam folders and confirm your email is correct.

Local settings like phone sync or notifications may reset, but your account data remains intact.

Sign in with the same method you originally used. Your account and connections will load automatically.

If the request hasn’t been accepted yet, you can find it in Requests & Blocks and cancel it. If the request was already accepted, simply disconnect from that user to stop sharing.

OneContact shows real people, and names aren’t always unique. Tap a profile to view more details and confirm the correct connection before sending a request.

You can search by username, first name, last name, email, or phone number. If none of those return results, they may have blocked you.

OneContact only requests permissions that support specific features:

• Contacts — to optionally sync your OneContact connections to your phone

• Notifications — to alert you when someone updates their info

• Camera & Photos — to add or update your profile and card photos

All permissions are optional, and you can manage or change them anytime in your device settings.

Only if you want OneContact to sync contacts to your phone. The app works without it.

Phone sync is optional and requires contact permissions. If permissions are denied, syncing won’t occur. Check your device’s settings to make sure OneContact has full contact access.

Open their contact details in your Contacts list. If you see an option to reconnect, the connection was removed by you or the other person. Reconnecting will restore updates once the request is accepted.

The other person hasn’t accepted or declined the request yet. Once they respond, you’ll be notified and their shared contact details will appear in your contacts.

No. OneContact never messages or contacts anyone without your action. Connections and invites only happen when you choose.

There isn’t one. Just fewer “Hey, is this still your number?” moments.

It can—but more importantly, it replaces outdated ones.

iCloud and Google Contacts store your copy of someone’s information. OneContact works through direct connections, so updates only happen when the other person chooses to share them. That means better privacy, clearer control, and fewer outdated details.

Because people forget, miss messages, or save it wrong. OneContact removes the human error.

If you requested account deletion, all data is permanently removed and cannot be recovered. If you simply signed out or stopped using the app, you can sign back in at any time to access your account and data.

Yes. We’re always improving OneContact, so features may evolve as we add updates and enhancements.

OneContact is currently available in the United States. We’ll share updates as availability expands.

When you disconnect, you’ll no longer see any information they shared with you, and they won’t see any information you shared with them. The only information visible after disconnecting is what each person has made publicly available in OneSearch. You can reconnect at any time, and they can request to reconnect as well. If you want to prevent future requests, you can block the user.

If you experience an issue or abusive behavior, contact us through the Contact Us section in the app or email onecontact-contactus@behappyinnovations.com. Our team will review and take appropriate action.

If OneContact is temporarily unavailable, your existing contact information remains unchanged. Updates will resume automatically once service is restored.

You can view all updates in the Activity section of the app. It shows changes made to your account and updates from your connected contacts.

Each user is responsible for keeping their own information up to date. OneContact reflects the details users choose to share, but does not verify or modify that information.

Sign back in and pick up right where you left off.

Sign back in on a new device and your info is still there.

Yes. You can view updates the Activity section so nothing feels mysterious.

They can change it again instantly. You’ll always have the latest version.

Yes. Couples and families often use OneContact together. Each person has their own account, so everyone manages their own info and shares it with the people they choose.

Update it once in OneContact, and your connections stay in sync automatically.

Absolutely. No more guessing who moved.

All of the above. OneContact lets you create different cards for friends, family, and work, so you can share personal info with friends and professional info with colleagues—without overlap.

Deleting the app stops phone syncing, but your OneContact account stays intact and your connections continue to update.

You can share your OneContact card or QR code with them. They’ll be prompted to download the app and accept your connection. Or, they can sign up on their own and use OneSearch to find and connect with you.

OneContact keeps its own synced contact info so you always know what’s current.

Immediately. If they update it, you see it.

OneContact uses mutual connections so updates are shared intentionally and privately. Both people must agree to connect, which ensures control, prevents unwanted sharing, and keeps information accurate.

Blocking prevents a user from connecting or reconnecting with you. If you’re currently connected, you must disconnect first. Disconnecting removes shared contact details, and blocking stops future connection requests.

You can block a user in two ways:

1. From OneSearch — Find the user in OneSearch and block them directly.

2. From an existing connection — Open the contact, disconnect, then block the user from there.

Disconnecting removes shared contact details from both users’ devices. Blocking prevents the user from sending new connection requests or reconnecting.

OneContact is built with privacy and security in mind. Your information is stored securely, access is limited to the connections you approve, and we do not sell or share your data.

You can read our full Terms of Service on our website. It outlines the rules, responsibilities, and conditions for using OneContact.

https://www.behappyinnovations.com/onecontact-terms-of-service 

Our Privacy Policy is available on our website and outlines what information we collect, how it’s used, and the steps we take to keep it secure.

https://www.behappyinnovations.com/onecontact-privacy-policy 

Passwords must be at least 8 characters and include one uppercase letter, one lowercase letter, one number, and one special character. We require strong passwords to help protect your account and the sensitive information you choose to share. This added security helps prevent unauthorized access and keeps your data safe.

No. Ever. Your data is yours.

No. OneContact does not upload or store your phone’s contacts. If you choose, it can one-way sync your OneContact connections to your phone so your saved contacts stay up to date—but your existing phone contacts are never copied into OneContact.

Anytime. One tap, and the connection is gone.

Yes. You’re in full control—share different info with different people.

Only the people you explicitly connect with.
