Why is messaging with OneTime secure?

Messaging with OneTime is 100% secure and private since the connections to OneTime servers are encrypted and therefore contents of messages are encrypted. Messages that have been delivered by the OneTime Service are not copied, kept or archived by OneTime. The OneTime Service is meant to be a SMS replacement, using data service through a user’s phone (either via cell network or wifi).

Users type their messages, which are sent via data service to our servers, and routed to the intended recipient (who must also be a OneTime user), if that recipient is online. If the recipient is not online, the undelivered message is held in OneTime’s server until it can be delivered. If the message is undelivered for maximum thirty (30) days, the undelivered message is deleted from our servers.

Once a message has been delivered, it no longer resides on our servers. The contents of any delivered messages are not kept or retained by OneTime — the only records of the content of any delivered messages reside directly on the sender’s and recipient’s mobile devices.

If you would like to learn more about our Privacy Policy, please take a look at our Privacy Notice.

Cheers,
OneTime Support Team

How to register with OneTime for the FIRST TIME?

After downloading the app from the Google Play Store or the iTunes App Store you have to register your phone number to use OneTime.

When registering OneTime the number you are registering has to be the one linked to your current SIM card because you have to send a SMS from your phone.
For a successful registration you have to send a SMS from your phone and you’ll have to wait for confirmation from the server.

Enter the phone number for your phone.
- Type your country code in the box on the left.
- Enter your phone number in the box on the right. Do not put any leading 0s before your number!
Click Next and confirm on the next screen that your number is correct.
You have to accept the Terms of service and privacy policy.
- Click on Terms of service and privacy policy to read them. To accept the Terms of service and privacy policy slide the marker to on.
- ONLY if you were invited by a friend please enter the invite code you received with the invitation in the box on the right. If you didn’t receive an invitation leave the box blank.
For more information on invite code, please read here.
Click Register (Send SMS) and wait for confirmation from server. You should now see a time counter that counts from 1:20 downwards. After you received the confirmation you have successfully registered with OneTime.
- If registration was not successful and the counter run out, then you need to resend the SMS by confirming "Trying again?"
- For a successful registration you have to send a SMS from your phone and you’ll have to wait for confirmation from the server.
Enter Name which other users see if you are not in other users' phone book and press Next.
- Click the camera symbol to upload a profile picture
Now you are ready to start chatting with your friends!

Cheers,
OneTime Support Team

Why is my registration not successful?

To register the app successfully you need to send a SMS to the server. A common error is that the SMS is being sent from a number being different than the number that was entered on the registration screen. For example the SMS was sent from +44 744 902808 7 but you entered the mobile number like +44 744 90280 8. If this is the case registration will not work. Also make sure when registering you have a good reception e.g. like 3G or WIFI.

Cheers,
OneTime Support Team

Why does OneTime use my phone number and my address book?

We ask for your phone number because that is how OneTime routes chat messages between you and your contacts, similar to how the SMS system would.

Your address book data is private to you. No one else using OneTime has access to your address book data, unless you share the data. We value your privacy and we have not, do not, and will not ever sell your personal information to anyone. If you would like to learn more about our Privacy Policy, please take a look at our Privacy Notice. In order to prevent and reduce unsolicited spam messages, as well as to improve your in-app experience, OneTime uses the phone numbers from your phone's address book. OneTime does not store any of your information on anyone else's systems. OneTime looks at the phone numbers in your address book, then checks to see which of those numbers are verified in OneTime. This allows any OneTime user from your address book to appear as contact in your Favorites screen and appear highlighted in your Contact screen. During this entire process, only the phone numbers are sent to OneTime for lookup, securely, over an encrypted connection. No other information, such as names, emails, and addresses are sent. So that you know who you are chatting with, the app then displays the names from your address book.

Cheers,
OneTime Support Team

How do I add contacts to OneTime?

OneTime can find which of your friends are using OneTime quickly and easily. OneTime reads your contacts' phone numbers from your phones address book and automatically adds them to OneTime. Your contacts that have OneTime accounts will automatically appear in the Contacts list in OneTime.

If you would like to add a new contact to your Contacts list on OneTime, simply enter their name and number into your phone's address book, then refresh your Contacts list:

Android

Enter your contact in your phone’s address book
Open OneTime.
Go to the Contacts tab the Refresh button.

iPhone

Enter your contact in your phone’s address book
Open OneTime.
Go to the Contacts tab.

+ [Country Code] [Full Phone Number].
Also be sure to omit any leading 0's from the phone number.

Cheers,
OneTime Support Team

How do I filter my contacts in OneTime for Onetime Users?

If you type in search box the word "OneTime" then all OneTime Users in your phone book will be displayed.

Cheers,
OneTime Support Team

What are those check marks next to my messages?

Check marks will appear next to each message you send. Here is what each one indicates:

message successfully sent.
message successfully delivered to the recipient's phone.
a ‘seen by’ message indicates that the recipient has read your message.

In a group chat, the second check mark will appear when all participants in the group have received your message.

If you only see a single check mark next to your message, there is likely nothing wrong with OneTime or your phone. There may be several reasons why your message has been sent, but not delivered to your chat partner:

Their phone might be off.
They might have turned notifications off on their device, to learn more about notifications see here.
They could be sleeping, especially if they live in a different time zone.
They might be experiencing network connection issues.
They might have seen the notification on their screen, but did not launch the app.
They might have blocked you.

What is a Group Chat?

The Group Chat feature lets you chat with a group of people at once. It is a great way to stay in touch with your family, friends and colleagues. In addition to the maximum number of people you can add to a group, there are a few more things to keep in mind about Group Chat:

There is no limit on members of a group but we recommend less than 100
There is no limit to the number of groups you can create.
Every group has one admin. Only the admin can add or remove participants.
Only an admin can make another participant to be the sole admin.
If the admin leaves the group, a new admin will be randomly assigned.
You can always control your own participation in a Group Chat, by staying in or leaving the group when you wish. Remember that only the group admin has the ability to add participants. If you have any questions about being added to a group, or prefer not to be added, please speak to the group admin.

Making a phone call/video call via OneTime

With OneTime Calling/Video Calling, you can place a call to your friends using OneTime for free, even if they’re in another country. OneTime Calling/Video Calling uses your phone’s Internet connection rather than your cellular plan’s voice minutes. Data charges may apply.

Make a OneTime call

open the chat with the person you want to call
tap on the options button on top and select Call
Wait for your contact to pick up
If your contact is not available you get the option to leave a message or to call his number the normal way.

Receiving a OneTime call
When someone calls you, you will see an incoming OneTime call screen. You can tap

The green button to answer the call,
The green camera button to answer as video call or
Tap the red button to decline the call.

If you answer as video call your camera will be activated automatically and your contact will get informed that you replied with video call. Your contact then can then decide if he also wants to activate video call. If he doesn’t activate video call then both will only see your video feed.

Make a OneTime video call

Open the chat with the person you want to call
Tap on the options button on top and select video call.
Wait for your contact to pick up.
If your contact is not available you get the option to leave a message or to call his number the normal way.

To make a successful video call your contact has to activate his camera during the call, either with accepting the call with the camera button or pressing the camera button during the call. If he doesn’t activate video call then both will only see your video feed.

Receive a OneTime video call
When someone video calls you, you will see an incoming OneTime call screen. You can tap

The green button to answer the call,
The green camera button to answer as video call or
Tap the red button to decline the call.

If the caller made a video call to you, you can decide if you want to activate the camera or not. To do this you can either take the call with the green camera button and your camera will be activated automatically or you can press the camera button during the call to activate your camera. Both parties can activate and deactivate their cameras at will during the call and therefore change a call to a video call or the other way round.

Note: you can’t access 911 and other emergency service numbers through OneTime. You must make alternative communication arrangements to make emergency calls.
