Beat the Traps
Last updated 27 September 2026
Written for the students who use this. The full notice is underneath.
What we know about you
If your school set you up: your first name and surname, the username we made for you, and your teaching group — never an email address. If someone bought it for you: your first name and surname and the username we made for you — again, never an email address. If you bought it yourself: your name, your email address and a record of your order. In every case, also your progress through the modules. That is genuinely it.
Why we have it
To let you in and keep your progress. If your school set you up, your teacher can see how you are getting on; if someone bought your access for you, so can they. You sign in with your username, or with your email address if you bought it yourself, and a password that only you know.
What about all my answers?
Your progress is saved on your phone and also sent to us, so it follows you to another device. If your school set you up, your teacher can see which traps you have beaten, which answers you chose first, and whether you have finished any homework they set. If someone bought your access for you, they can see the same, apart from homework. Neither can see your worked-example picks or your Exam Ready answers. If you bought it yourself, nobody else sees your progress.
Are you tracking me?
No. No analytics, no adverts, no pixels, nothing following you to other sites. We are not building a picture of you and nothing about you is sold or handed on.
Can I see it, or get rid of it?
Yes. Email privacy@sakatismaths.co.uk and ask, and we will send you what we hold or delete it. It is free and we will come back to you within a month. If your school set you up, we will let your school know.
What if I think you have got something wrong?
Tell us at privacy@sakatismaths.co.uk. We have to reply to say we have got it within 30 days, then look into it properly and tell you what we found. If you would rather go to the regulator instead, or as well, that is the Information Commissioner’s Office at ico.org.uk.
How long do you keep my email?
While you have access, and for a year after it ends in case you come back. Then it goes.
Beat the Traps is a revision app for Edexcel A level Mathematics, run by Leonie Sakatis, trading as SakatisMaths (“we”, “us”).
If your school set you up, your school decides that you use Beat the Traps, which pupils have accounts, what name goes in, who can see your records and when they are removed. In data protection law your school is the controller of those records and we are its processor: we hold them on your school’s behalf, only to run the service, and never for anything of our own.
If you are a teacher with an account, or your access was bought rather than arranged by a school, we are the controller of the information we hold about you. If you are a teacher, your name and email address came from your school: from its order, or from a colleague who added you.
You can reach us about anything in this notice at privacy@sakatismaths.co.uk, or by post at Leonie Sakatis / SakatisMaths, Lytchett House, 13 Freeland Park, Wareham Road, Poole, Dorset BH16 6FA.
We are registered with the Information Commissioner’s Office, registration number C2024586.
How you sign in. If you bought access for yourself, we hold your email address and use it to let you in. If your school set you up, we hold your first name, surname and teaching group, which your school gave us, the date you joined that group, and a username we made from them; you sign in with that username and a password only you know. If someone else bought your access, they gave us your name, and we made your username from it. Without one of these there is no way to give you access to something that has been paid for.
If your school set you up, the lawful basis for your records is your school’s, and your school’s own privacy notice explains it. We hold your name, username, group and progress because your school has asked us to, so that your teacher can see how you are getting on — never for our own research, statistics or to develop the app. For teachers with an account, and for anyone who buys access, our basis is that we need the information to provide what you have signed up for (performance of a contract). If someone else bought your access, the basis is explained under If you bought Beat the Traps yourself, below.
Your progress through the modules. This is kept on your phone or computer so the app remembers where you were, and a copy is sent to us each time you save. For school users it is what your teacher’s screens show: which traps you have beaten and when, your warm-up and practice scores, the answer you chose first on each practice question, and whether you finished any homework set for your group by its due date. If someone bought your access for you, they see the same, apart from homework. It is personal information we hold, and this notice applies to it.
Where it is stored. Everything we hold is stored in the EU, on Cloudflare’s servers, and cannot be moved elsewhere without a change to this notice.
Nothing else. We do not use analytics, advertising, tracking pixels, or any tool that follows you around. We do not build a profile of you, we make no automated decisions about you, and we do not sell or share your information with anyone for their own purposes.
Cloudflare hosts the app and the database that holds what we keep about you, and sends our emails. Cloudflare’s servers see the usual technical information any website sees — your IP address and what your browser asked for — in order to deliver pages and keep the service secure. Cloudflare acts on our instructions and cannot use your information for its own purposes.
Nobody else is involved in using the app. It loads everything it needs from our own site and Cloudflare, so using it does not put you in contact with any other company. The sign-in page loads Turnstile from Cloudflare, which checks that a person, not a program, is signing in; to do that it sees your IP address and some details of your browser, which Cloudflare also uses to improve Turnstile, as its Turnstile privacy notice explains. Buying access is the one exception: Stripe takes the payment, as explained under If you bought Beat the Traps yourself, below.
The sign-in sets a cookie so you do not have to enter your password on every page. The app stores your progress in your browser. Both are needed for the app to work at all, and neither is used for advertising or tracking, so we do not ask you to agree to them separately. Clearing them will sign you out. Your progress comes back the next time you open a module, because we hold a copy.
Your progress follows you: sign in on any phone or laptop and it is there. If you tap Start again on a module, that module’s progress is cleared everywhere, including from your teacher’s screen or the screen of whoever bought your access.
We keep what we hold about you for as long as you have access, and for twelve months afterwards, so that access can be restored if you come back for a resit or a second year. After that it is deleted, progress included. The one exception is the record of a purchase, which HMRC requires us to keep for longer: see If you bought Beat the Traps yourself, below. If your school set you up, your school can ask us to delete your records sooner; we never keep them longer.
We keep a short record of attempts to sign in, reset a password or pay — when, and from which address — for as long as it takes to spot and stop someone guessing passwords or misusing a form, then it is cleared.
Who is responsible. With school accounts, the school decides what happens to pupil information and we act on its instructions. With an account someone buys themselves there is no school, so we are responsible. That is Leonie Sakatis, trading as SakatisMaths, at the address above. Registered with the ICO, number C2024586.
What we hold. From whoever buys: their name and email address, the country of their billing address, a scrambled copy of their password that we cannot read, what they bought and when, the two boxes they ticked and the time they ticked them, and a payment reference from Stripe. We never see a card number.
About the person using it: first name, surname, username, a scrambled password, which traps they have beaten and the answers they chose, and when they last signed in. If you bought it for yourself, both lists are about you.
Why we are allowed to hold it. Your own details, because we need them to give you what you paid for. The details of someone you bought it for, because you asked us to set them up and you want to see how they are getting on — they are not part of the contract, so we rely on legitimate interests, and we weigh their interests heavily since most of them are under 18. They can object at any time. The order and the ticks, because tax and consumer law require us to keep them.
Who can see it. Leonie Sakatis, and nobody else, because there is nobody else. Whoever bought the access sees that student’s progress and can reset their password, and the student’s library tells them so. We do not sell anyone’s information, run adverts, use trackers, or study anyone’s progress to build products.
Who else is involved. Cloudflare hosts the site and the database. Stripe takes the payment; its privacy notice explains what it does with your card details. Cloudflare sends our emails. Nobody else.
How long we keep it. The account, including all progress, goes 12 months after access ends. At the same time your name and email address are taken out of the order record, which is kept for as long as HMRC requires: five years after the January deadline for that year’s tax return.
If someone bought this for you. Your name, your progress and the answers you choose are held in your account. The person who bought it, whether a parent, carer or tutor, can see them and can reset your password. Nobody else can. Even though someone else paid, the information is about you: you can ask us what we hold, ask us to correct it, or ask us to delete it. Email privacy@sakatismaths.co.uk.
You can ask us to give you a copy of the information we hold about you, correct it, delete it, restrict what we do with it, or object to us using it. You can also ask for it in a portable form. There is no charge, and we will respond within one month.
To do any of these, write to privacy@sakatismaths.co.uk. If your school set you up, we will tell your school and work with them to answer you.
If you are unhappy with how we have handled your information, you can complain to us directly. Write to privacy@sakatismaths.co.uk and say that you are making a data protection complaint. We will acknowledge it within 30 days of receiving it, look into it without undue delay, keep you posted while we do, and tell you the outcome and how we reached it.
Please write rather than sending a message on social media. It is not a secure way to send information about yourself, and we do not reply to private messages there.
You can also complain to the Information Commissioner’s Office at any time, whether or not you have complained to us first. The ICO is at ico.org.uk, or 0303 123 1113.
Most people using Beat the Traps are sixteen, seventeen or eighteen. Everything above applies to you in exactly the same way, and there is a shorter version at the top of this page written for you. If you would rather a parent, carer or teacher dealt with us on your behalf, that is fine — tell us and we will deal with them instead.
If we change how any of this works we will update this notice and change the date at the top. If the change is a significant one, we will tell the email address we have for you, or your school if they arranged your access.
