The app sits on your child's device and runs with their consent. It automatically checks their activities and interactions. It compares these against Danger Detection algorithms which has put NSPCC and CEOP advice into code and has been further curated by a panel of experts. If it identifies potential dangers, it sends warning flags to alert you in a timely manner by email with signposts to tips on what to do. You can also log in to your dashboard to see these flags and other patterns and trends.

It is both a nod to George Orwell’s 1984 and a reimagining how a Big Sister used to protect their siblings before the internet.
In 1984 there was an all seeing, sinister Big Brother. Big Sister is all seeing but kinder and definitely not sinister. She’s on your side.
Before the internet, you’d expect a Big Sister to know much more than their younger sibs and also to know what they were “up to”. If they were doing something potentially dangerous they would let the parent know without ruining the kid’s privacy. Our Big Sister does this too but she is just plugged onto their devices and super charged with expert advice and AI.

Big Sister is the only app that balances privacy and safety for children and teenagers online. Many apps focus on privacy but leave parents in the dark about potential dangers and how to address them. For example, Android Family Link only tracks app usage time, failing to alert parents about harmful content, such as children spending hours searching for dangerous topics on YouTube. On the flip side, some apps let parents see everything, which can push children and especially teenagers to find a way around the controls. Big Sister solves this by teaming up with an expert panel to help parents spot risks while keeping kids' privacy intact. With a mix of expert advice and smart AI flags, Big Sister keeps parents informed without invading their child's space. Big Sister is the perfect solution for keeping kids safe online!

Yes absolutely. We have encrypted the data end to end. We are Cyber Security Plus standards which is the standard to which the government protects their data. To us your data is as important as state secrets. We monitor our infrastructure, activities and continually update our systems to guard against potential threats. We minimise the amount of data stored so that the threat surface is minimised.

We start with the free trial so you can check it suits your family. Then we charge a flat rate every month. If you choose the annual cost you get a discount. If you want to cancel you can and you wont be charged on the next billing cycle. That’s it, simple.

We always suggest open an honest discussions and you legally have to have consent from your child.
For younger children the deal might be: “you can have this device but if you do you have to have Big Sister running on it to keep you safe.”
For an older child more nuance will be required but teenagers on our expert panel appreciate that their privacy is maintained and their parent is then reassured.

This is a red flag sent immediately to you. It could be a completely innocent reason- maybe the phone has been factory resetted or is just out of battery? But you need to know that the protection you’re counting on is running.

Yes. Unlike other solutions out there it covers all the apps and images that your child can see on their devices.
