Overall safety rating:

Our overall rating for Tellonym


As Tellonym is an app that lets you share and ask questions anonymously, we don't think it's suitable for under 18s. There is also a risk your child could talk to someone they don't know and come across adult content they might find upsetting. 

There are some filters available to help stop certain topics and content appearing on your feed, but there's no guarantee these will always work. 

Safety features

There is no age verification process in place even though the app is rated 17+. This means it's really easy for a child of any age to sign up. 

There are no other safety features available and accounts are set to public by default. This means there is a risk your child could be contacted by someone they don't know. 

Privacy & location

Accounts on Tellonym are set to public by default meaning anyone can send them messages. We would recommend making their account private so they can't be contacted by people they don't know. 

There is a feature that lets you share your location. However, this is switched off by default. You should check your child's account settings to make sure this is turned off. 

Reporting & blocking

There are reporting and blocking tools available on each user profile in the right hand corner of the screen. Tellonym also has Community Guidelines outlining how people should behave on the app. 


We didn't come across any inappropriate content while exploring the app. However, as the content is user-generated and anonymous there is a high risk your child could be sent something that worries or upsets them.

Top tips for staying safe

Sitting down with your child and exploring their favourite app or game is a great way for you to learn more about what they like to do online.

You can ask them why they like to use an app or play certain games, as well as who they’re talking to and what sorts of things they’re sharing.

You can also read our Net Aware reviews for tips on how to keep kids safe on popular apps, sites and games.

Help your child think about what they share online and who sees it. Compare it to what they would be happy to share offline.

Use examples that are easy for them to understand: “You shouldn't give your number to somebody you don't know on the street. Is somebody online you don't know any different?”

Listen to their answers. And be positive and encouraging.

Remind them that they shouldn’t share private things, such as:

  • personal information, like names, emails, phone numbers, location and school names
  • other people's personal information
  • links to join private group chats
  • photos of themselves
  • photos of their body, such as sexual photos or videos.

Explain that you understand the internet is a great place to play, create, learn and connect. But remind them they can talk to you if anything upsets or worries them.

Reassure them that you won’t overreact – you’re just looking out for them.

It’s important to remind your child that they can talk you, another adult they trust, like a teacher, or Childline about anything they see online.

Because Tellonym encourages people to ask and answer questions anonymously, there's a high potential for cyberbullying and online abuse.

In settings, there's a tool called Wordfilter that lets you add up to 10 words so messages containing them won't be sent to you. You can also set language filters from very low to very high. Take the time to explore these filters with your child and decide what's right for you.

If your child comes across something upsetting - about themselves or someone else - they might want to block the user that posted it. Tellonym has instructions on how to block other people.
Explore these safety features together and remember to let your child know that they can always talk to you about worrying things they see online. 

It's important to check the privacy settings on your child's Tellonym account. Most settings are set to public by default, so we recommend changing these to private. This way your child shouldn't be contacted by people they don't know and their location will be kept private.

You can visit Tellonym for specific information on privacy options.

Talk to your child about the different options and decided together which ones you should use.
