Why do you need to send me push notifications?

Every time your friends invite you with treffn, we need to let you know. With push notifications turned off you won’t get any invites as well as no updates in the chat. Please refer to our tutorial on how to turn push notification on.

Why do you need to know my current location?

To invite someone to your current location, treffn needs to know where you are. We do not store or process this information in any way except to provide you functionality. For example, we use that information to give you directions and calculate travel duration.

Why do you need access to my adress book?

With the help of your address book, treffn identifies and displays contacts who are also using treffn. But do not worry: No names, photos, email addresses, birthdays etc. will leave your phone, only phone numbers. And even those in an encrypted format. No one, not even we, can deduct anyone’s real phone number from what we transmit.

What information from my address book do you store on your servers?

We do not store anything on our server about you or your friends – except your phone numbers in an encrypted format. No one, not even any of us, can deduct anyone’s real phone number from what we store.

Profile & Appearance

My profile picture looks grainy and low qualtiy!

If the quality of the picture is bad, simply go to your profile and select the same photo as your profile picture again. Treffn will then create a high-quality version for use in the app.

How does treffn define policy

Can I invite people without treffn app?

Yes, treffn sends invitations to your contacts even when they have not installed treffn app yet. It will send a text message with an invitation and a link to a mobile website that offers nearly the same functions as the app. The message is sent via your mobile network provider to you guest and you need to confirm it.

Can user stalk, invite non-friends or anonymously?

No, to send an invitation it is mandatory to know the other person’s mobile phone number. With treffn you cannot select persons outside of your personal contacts.

treffn does not transfer your position (no blue dot on a map) and will only send messages you initialized.

Does treffn store my phone number?

No, treffn needs to register your device. It requires your phone number to generate an individual ID. To verify your device treffn sends a PIN via text message once.

The ID is used to send messages and to link meetings with your device. But treffn’s database doesn’t store you name, phone number nor your position.

When I send an invitation, will the participants receive my phone number?

No, invitations are sent without transferring your phone number.

Only non treffn user may see your number when sending an invitation by text message, because text messages (sms) always transfer a phone number.
