Slate turns the phone already in your pocket into a single-purpose reading device for your child. Open Slate Time and the phone becomes a slate: a library of classic tales and nothing else. No browser. No feed. No notifications. No next-episode autoplay waiting to catch a five-year-old's attention. When the day's reading is done, Slate says so and stops - it does not hand your child an open phone. WHAT IS INSIDE A library of classic tales - Aesop, Panchatantra, and the stories that have been told to children for centuries - retold and illustrated for the age you set. Every tale is told more than one way: picture-play for the youngest, read-along with narration for children finding their feet as readers. Narration is always available, so a child who cannot yet read can still use Slate alone. Reading earns play. Finish a tale and your child unlocks a few minutes of quiet play - a small, gentle game with a clear end, not a feed without one. However many minutes they earn, the daily limit you set still holds, and you can switch play off entirely. The screen is styled to read like paper: grayscale, high-contrast, glow-free. It is not an e-ink display and we will not pretend it is. It is your phone's own screen, calmed right down. LEAVING SLATE TIME, HONESTLY Slate Time runs under Guided Access, Apple's own way of keeping an iPhone on a single app. Before a session starts, Slate waits for you to turn Guided Access on with three presses of the side button; if it is not set up yet, the screen shows the one-time steps (Settings > Accessibility > Guided Access). Your child cannot leave Slate Time from inside the app. Ending it takes three presses of the side button and your Guided Access passcode, and the session ends the moment Guided Access does. Slate does not use Screen Time and asks for no Screen Time permission. WE COLLECT NOTHING ABOUT YOUR CHILD Not "we anonymise it". Nothing about your child is ever sent anywhere. There are no child profiles, no progress files, no behavioural records, and no third-party analytics or advertising SDKs anywhere in this app. A kid space is a nickname and an age range that you choose, and it never leaves the phone. Minutes read and minutes earned are calculated on the device, shown to you, and never transmitted. What we do hold is your own phone number, because that is how you sign in and how your subscription is recognised. That is the entire list. We are governed by India's DPDP Act, and you can ask us to delete your data at any time - including from inside the app. PRICING Slate begins with 7 days of full access, free. No card, no trial that quietly becomes a charge. After that: - Slate Monthly - Rs. 149 per month - Slate Annual - Rs. 999 per year (about 44% less than paying monthly) One subscription covers every child on the phone. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is switched off at least 24 hours before the end of the current period. You can manage and cancel your subscription in your Apple Account settings after purchase.
