Independence for them, peace of mind for you.
Sayph is a phone designed from the ground up for childhood — calls, texts and the real world, without social media, app stores or the open internet.

Standard smartphones aren't designed for children
Most phones give children unrestricted access to social media, addictive apps and harmful content. Parental controls are easy to bypass and hard to manage. Sayph is different: not a smartphone with controls bolted on, but a phone built to be safe from the ground up — so you can say yes to a first phone without saying yes to social media.
- No app store — nothing risky by default
- No social media or addictive content
- Built-in safety that children can't disable
- Full parental visibility via the Sayph portal
Everything a child needs. Nothing they don't.
Sayph puts parents in control. No unsafe apps. You decide who they can contact, and set times when the phone works.
Parent-approved contacts only
Only numbers you approve can call or message this phone. No calls from unknown users.
No social media. No app store.
Nothing risky or addictive, by default. Addictive apps have no place in childhood, but this shouldn't make your child stand out.
Real-time location
Check where they are whenever you need to — on the walk home, at the sleepover, at the match. Peace of mind, on demand.
Tough to crack
With no app store, no default browser and parent-only installs, Sayph is much harder to circumvent than standard parental controls.
Safer photos & messages
Select which contacts can exchange photo messages with your child. If unsure, these are blocked by default.
Hassle free management
No juggling parental controls. Message summaries are designed to flag anything that may need your attention — so you stay informed without reading every text.
“Overprotection in the real world and underprotection in the virtual world are the major reasons why children born after 1995 became the anxious generation.”
Set up in minutes. Peace of mind for years.

Frequently asked questions
Everything you need to know about Sayph.
8 to 16. Like Smartphone Free Childhood, we believe that in an ideal world children wouldn’t need phones at all — and that holding off for as long as you can is the right instinct. But when the time comes for your child to stay in touch and have a little independence, that first phone shouldn’t be an open smartphone. Sayph lets you say yes to calls, texts and knowing where they are, without saying yes to social media, an app store or the open internet.
Sayph is built to be far harder to get around than standard parental controls. There’s no app store, no default browser, and the operating system itself is restrictive — there are no settings for a determined child to find and switch off. No device on earth is tamper-proof, but unlike bolt-on controls, Sayph’s restrictions are the phone, not an app running on top of it. Only apps we’ve screened and you’ve approved can ever be added.
No. We've heard too many stories about what happens when children are allowed to roam free on social media, and honestly, we don't believe the big tech firms can be trusted to safeguard our children. The tech firms have themselves chosen 13 as the age when they want children to start using their products. We believe if governments were serious about prioritising children's mental health and wellbeing, they would ban social media use before 16.
We are working on a Sayph browser that will allow safer internet browsing, with filtering & monitoring available via the Sayph Space parent portal. When we do introduce our browser, it will still be possible to exclude it from your child's phone, keeping them off the internet entirely.
We believe that safer phones should be available to all children, so have worked hard to keep the costs low. The 4G Sayph Phone is available to buy now for £189. Monthly subscription from £4.99/month. You will just then need a SIM & call plan (available from £2–3/month).
Parents can select which contacts are approved for exchanging MMS (picture messages) with. This is to reduce the risk of children and young people either being sent images they don't want to see, or pressured into sending something they shouldn't. We are developing a system designed to allow effective monitoring of MMS images, so we can enable safer photo sharing.
The Sayph phone works with any standard UK SIM card, including cheaper talk-and-text-only plans. You buy the SIM yourself from any provider – Sayph does not sell SIMs. You can use a SIM you already have or pick up a low-cost plan from providers like Smarty, Giffgaff, or Tesco Mobile. We recommend looking for plans that include MMS messages, as these can be costly on some networks. For example, Smarty SIM-only plans start from around £2–3/month and include MMS as standard. The Sayph phone uses a nano-SIM and supports all major UK networks (EE, Three, O2, Vodafone and their MVNOs).
Calls and texts work on any SIM. However, live location tracking, remote monitoring and online maps need a mobile data connection to work when your child is away from WiFi. With a talk-and-text-only SIM, these features update only when the phone reconnects to WiFi, and maps work only for areas already downloaded over WiFi. If you want reliable location tracking and maps when out and about, choose a SIM with a small data allowance. If you’re happy for those features to work on WiFi only, a talk-and-text-only plan keeps costs down.
No — and we’d be suspicious of any product that claimed to. Sayph gives you visibility and control, but it doesn’t monitor your child’s wellbeing in real time and it isn’t an emergency service. It works best alongside the conversations you’re already having. We also encourage you to be open with your child about what the phone shares with you — in our experience, that openness is what builds trust rather than resentment. If you’re ever worried about a child’s immediate safety, call 999.
As little as possible, for as short a time as possible. Messages, call logs and location history are encrypted, visible only to you (never to Sayph staff), and automatically deleted after a maximum of 30 days. We don’t sell data, we don’t profile children, and our AI summary provider is contractually barred from training on your family’s data. Full details in our Privacy Policy.
Built for childhood, not for scrolling.
Give your child the freedom to call, text, and explore the real world — without handing them the digital one.
What if my child is not ready yet?
Like the Smartphone Free Childhood movement, we believe children shouldn’t be handed powerful tech before they’re ready. But when the day does come that your child needs a phone, there shouldn’t be a cliff–edge from no phone straight into the full adult internet. Sayph is the gentle step in between — ready for whenever that day arrives.
