3toGo is made by Micro Habit Labs (Tanvir Singh Manku). It helps you manage your own screen time by asking short language-learning questions before unlocking apps you choose to block. Your Screen Time data and your learning stay on your iPhone. The only things that leave it are the app events described under Analytics and advertising measurement, the anonymous usage counts described under Usage data we collect ourselves, and anything you choose to send us from the Support screen.
3toGo uses Apple's Screen Time (Family Controls) frameworks with your explicit permission, solely to block and unblock the apps you select on your own device. The identifiers of your selected apps and all related usage state never leave your device. We do not collect, transmit, sell, or share Screen Time data with anyone, and we do not use it for advertising or measurement of any kind.
Your question history, streaks, points, and progress are stored locally on your device. So are your XP, emergency unlocks and vacation days. There's no account, so none of it syncs to your other devices. The questions, your answers and your words are never uploaded. The app does send us anonymous counts about how it is used (how many questions a gate took, for example), described under Usage data we collect ourselves.
Subscriptions are processed entirely by Apple. We receive no payment details. When a free trial starts or a subscription is paid, the app tells Meta which plan it was and the currency, and for a payment the price, as described below.
3toGo includes the Meta (Facebook) SDK so we can measure whether our ads lead to installs and subscriptions. The SDK reports these events to Meta:
With each event the SDK also sends basic device details such as your device model, screen size, iOS and app version, language and time zone, your IP address, and a random ID the SDK creates for this install of the app. It can also send Meta crash and diagnostic information that isn't linked to you.
It does not receive your Screen Time data, the apps you block, your answers or your progress, because the app never gives any of that to it, and there's no account to share.
Once you have an active free trial or subscription, 3toGo asks you once, the next time you open it, with Apple's standard prompt, whether it may track you. If you allow it, the Meta SDK also sends your device's advertising identifier with events from then on (such as app opens and subscription payments). Meta can then connect those events to the ads you saw and to other information it holds, to measure our ads and decide who sees them.
If you don't allow it, or you're never asked, iOS doesn't give the app or the SDK your advertising identifier, and Meta measures the events in aggregate. The events above are still sent either way.
You can change your answer any time in iOS Settings, Privacy & Security, Tracking.
Meta is the only company the app shares data with for advertising measurement. Supabase only hosts our own database for us and may not use what is in it. Its terms for businesses require it to protect this data at least as well as this policy does, and its Privacy Policy explains how it keeps and deletes it. There are no other third-party analytics SDKs or trackers in the app.
If you've turned on sharing with app developers in iOS Settings, Apple may also send us crash reports from your device. That's Apple's setting, and you can turn it off there.
Since version 1.0.5 the app also sends a small set of usage events to our own database, so we can see where people get stuck and whether the app keeps helping after the first week. These go to a database we control, hosted for us by Supabase in the United States, and to nobody else. They are not used for advertising and are never shared with Meta.
Each event carries a random install ID the app makes up the first time it runs (it is not your Apple ID, advertising ID or anything that names you), the app and iOS version, your device model, your App Store country and your language. The events are:
Not sent: the questions, your answers, your words, your streak, the apps you block, or anything typed anywhere except the Support screen. Supabase, like any server, sees your IP address while the app is connected to it; we do not store it with the events. We keep these events for up to 24 months.
If you write to us from Settings, Support and feedback, we receive what you typed, the email address if you chose to add one, the app version and the install ID above. We use it only to read and reply. It is stored in the same database, and a copy is emailed to our support inbox (sent through Resend, an email delivery service) so we see it straight away. Both are deleted when the conversation is over, and in any case within 24 months, or sooner if you ask.
We don't keep a copy of your Screen Time data, your answers or your progress; our own database holds only the usage events and support messages described above. Deleting the app removes most of its data from your iPhone. iOS can keep a small shared file the widget and blocking use (recent streak days, a few Spanish words and your blocked-app settings), and 3toGo clears the streak and words if you reinstall. To wipe your progress before you delete the app, use Reset 3toGo in Settings, Your data.
Deleting the app doesn't remove events Meta has already received. Meta keeps and deletes those under its Privacy Policy, and you can manage how Meta uses data for ads in your Meta account settings. We keep support emails only as long as we need them to help you, and we'll delete yours if you ask. To have the usage events for your install deleted, send a message from Settings, Support and feedback (it carries the install ID, so we can find them) or email us; we delete them within 30 days.
3togo.app and these policy pages are plain static sites. They set no cookies, run no analytics or trackers, and load no fonts from anyone else. Cloudflare hosts 3togo.app and GitHub Pages hosts these policy pages, and each gets your IP address and browser details when a page loads, because that's how the page reaches you. If you email us, we get your email address and whatever you write, and we use it to reply.
I sometimes email Spanish teachers and language schools about 3toGo. I take the name and work email shown on your school's public website and keep them, with a note of what I sent and any reply, in a private spreadsheet. I do this because I think the app is useful to Spanish teachers, which is a normal business reason to get in touch. Reply "no" to any email and I'll stop. I then keep only your email address on a do-not-contact list so it never happens again, and delete the rest within 12 months of my last email to you, or sooner if you ask.
You can revoke Screen Time permission at any time in iOS Settings, and you can wipe your progress any time with Reset 3toGo in Settings, Your data. You can turn tracking off at any time in iOS Settings.
