KS2 Spelling privacy policy
Last updated 5 November 2026. This policy covers the KS2 Spelling app for iPhone, iPad and Android.
The short version
KS2 Spelling is made for children. There are no accounts or logins, no adverts and no tracking. Your child's name and progress are stored only on your device and are never sent to us or to anyone else. The only data that leaves the device is what is needed to process a purchase, if you buy a plan.
Who we are
KS2 Spelling is made by Blvck Studios Ltd (company number 12591076), registered in England and Wales at 124 City Road, London EC1V 2NX. We are the data controller for the app. Contact us at info@blvckstudios.co.uk.
What stays on your device
The app saves the following on the device it is installed on, and nowhere else:
- each child's first name (as typed in, up to four children on the Full plan) and the colour chosen for them
- test results, scores, practice words, streaks, badges and progress in Lex's Adventure
- settings, such as year group, voice speed, reminder time and an optional parent PIN (stored as a scrambled code, not the PIN itself)
We cannot see any of this. We do not run a server for the app, and the app has no way to send this information to us.
What we do not collect
We do not collect names, email addresses, phone numbers, photos, location, contacts or any other personal information. The app does not use the microphone or camera. It contains no adverts, no advertising identifier and no third-party analytics or tracking tools, and it does not build a profile of your child.
Audio and speech
Lex's recorded voice is built into the app, so it works offline and nothing is sent anywhere to play it. Any word that has not been recorded is read by your device's own text-to-speech. The app only uses voices that work offline on the device; it skips voices that would send the text to an online service.
Reminders
If a grown-up switches on daily practice reminders, your device asks for permission to show notifications. Reminders are scheduled on the device itself. No push notification service is used, and nothing is sent to us or anyone else to deliver them.
Purchases
The app is free to start, with optional Basic and Full plans. Purchases are made through the App Store (Apple) or Google Play (Google), which handle payment under their own privacy policies. We never see your payment details, name or email address.
To check which plan is active, the app uses RevenueCat, a subscription service. RevenueCat receives an anonymous app user ID that it creates (not linked to your name or your child's), your purchase and subscription details from Apple or Google, and the basic technical information needed to check a purchase, such as the app version, device type and store country. We do not send RevenueCat any personal information, or anything about your child or their progress. This is used only to unlock the plan you bought and to restore it on a new device, never for advertising or tracking. See RevenueCat's privacy policy.
Backups and sharing
A grown-up can save a backup file of everyone's progress, settings and children's names, and load it on a new device. The file is created on the device and only goes where you choose to save or send it, for example your files app, cloud storage or email. We never receive a copy. The same applies to progress reports and printable papers you choose to share or print. Anyone you give a backup file to could see what is in it, so keep it somewhere safe.
Children's privacy
KS2 Spelling is designed for primary school children and follows the UK GDPR and the Information Commissioner's Age Appropriate Design Code (the Children's Code). Data stays on the device by default, there is no profiling, no nudging to share, and no data is collected from children. For families in the United States, we do not knowingly collect personal information from children under 13, in line with the Children's Online Privacy Protection Act (COPPA).
Purchases, restoring purchases, links that leave the app, sharing reports and saving or loading backups are behind a parental gate (a sum for a grown-up to answer), so a child cannot do them alone. Grown-ups can also set a PIN to lock the parents area and settings.
How long data is kept and how to delete it
Everything stays on the device until you delete it. You can:
- remove one child, or reset one child's progress, in Settings
- delete every child, their names, all progress and every setting with Settings, then Start again from the beginning
- delete the app, which removes everything it stored on the device
Backup files you have saved are not deleted by the app; delete them wherever you saved them. Purchase records are kept by Apple or Google and by RevenueCat so your plan can be restored; you can manage subscriptions in your App Store or Google Play account settings, and ask us to request deletion of the RevenueCat record by emailing info@blvckstudios.co.uk.
Your rights
Under UK data protection law you can ask for a copy of personal data we hold about you, ask us to correct or delete it, or object to how it is used. Because the app keeps your child's information on your device, we hold none of it, but we are happy to help with any question. Email info@blvckstudios.co.uk and we will respond within one month. You can also complain to the Information Commissioner's Office at ico.org.uk.
Changes
If this policy changes we will update it here and change the date at the top of the page.
