Privacy Policy

• Screen Time data (iPhone). Swescroll uses Apple’s Family Controls and Screen Time frameworks to lock the apps you choose and measure your earned app time. Apple designed these frameworks so that this information is processed on your device. Swescroll never sees, stores, or transmits which apps you use, how long you use them, or which apps you have locked.
• The app lock (Android). Android has no Screen Time framework, so the lock works differently. After explaining why in the app, Swescroll asks you to turn on its “Swescroll app lock” accessibility service in Android Settings. The service is used for one thing only: noticing when an app you chose to lock comes to the front, so Swescroll can cover it with its lock screen. It is set up so that it cannot read what is on your screen, what you type, or what you tap. On phones where the accessibility service cannot be turned on, Swescroll can instead use Usage Access and Display over other apps for the same purpose. Either way, the list of apps you locked and the minutes you spend in them are processed and stored only on your phone and are never sent to us or anyone else. Swescroll does not collect a list of the apps you have installed. You can turn these permissions off at any time in Android Settings; the lock then simply pauses.
• Your learning data. Your vocabulary progress, spaced-repetition schedule, streaks, goals, and settings are stored on your device (and in your device backups — iCloud on iPhone, Google’s Android backup if you have it turned on). The app lock’s state is never included in Android backups. We have no server and no copy.
• No account. We do not ask for your name, an email address, or a login.
• Your reason for moving to Sweden. If the setup questions ask why you came to Sweden, that answer is used only to shape your study plan on the device. It is never sent anywhere, with or without your consent.

The first time you open Swescroll we ask whether you want to share anonymous usage data. Nothing is collected, queued, or written to disk before you answer: the analytics software is not even started until you agree. If you decline, or simply never answer, nothing about you is recorded and the app works exactly the same.

You can change your mind at any time under Settings → About. Turning it off stops collection immediately and clears the anonymous identifier we were holding; turning it back on starts a completely new one, unconnected to the old.

If you say yes, we use PostHog (hosted in the EU) to understand how the app is used so we can improve it. What we collect:

• Product events such as “onboarding step viewed”, “card answered (correct/incorrect)”, “level cleared”, or “trial started”.
• The fixed-choice answers from setup — which track you chose, your level, how long you have been in Sweden, when your test is, how confident you feel, what you want to change, and the study settings you picked — so we can see where people get stuck.
• A randomly generated anonymous identifier. It is not linked to your identity; we could not link it if we wanted to, because we do not know who you are.
• Basic technical details that come with every event, such as whether you use iPhone or Android, the system version, the device model, the app version, and the app’s language.

What is never included: your name, your flashcard answers, what you say in speaking exercises, which apps you lock or use, or any Screen Time or app-usage information.

Location. Every event we send is explicitly stamped to switch off IP-based location lookup, so no city, region, or coordinates are ever derived or stored. Your IP address still reaches our analytics provider as ordinary connection metadata when an event is delivered, as it does with any website — it is not used to locate you or attached to your profile.

These statistics are not used for advertising and are not shared with data brokers.

Two features send us something you wrote or chose. Both are entirely optional — the app works exactly the same if you never use them — and both work whether or not you agreed to usage statistics, because a message you deliberately send is not something we observe about you.

• Send feedback (Settings → About). The message you write is delivered to us so we can read it and act on it. The email field is optional: if you fill it in, we receive that address and use it only to reply to you. If you leave it empty, your feedback stays anonymous.
• Reporting a flashcard. If you flag a card as wrong or confusing, we receive which card it was, which reason you tapped (for example “translation is wrong”), and a short optional note if you choose to write one.

If you have not agreed to usage statistics, these messages are sent as a single one-off delivery carrying an identifier generated for that one message and never stored, together with the app version so we can reproduce the problem. There is no way for us to tie two such messages to the same person.

Pronunciation audio for words, sentences, and citizenship questions either ships inside the app or is downloaded from the app store that installed it — Apple’s servers as On-Demand Resources on iPhone, Google Play as Play Asset Delivery packs on Android. If a clip is not available yet, your phone’s built-in Swedish voice reads the text instead. We do not run an audio server and receive nothing when a clip is fetched or played.

Some cards ask you to say a Swedish sentence out loud. The first time, your phone asks for access to the microphone (and on iPhone, to speech recognition). You can decline, turn speaking cards off in Settings → Speaking exercises, or skip them for a while from the card itself.

When you speak, the audio goes to your phone’s own speech recognition, which turns it into text: Apple’s on iPhone, and on Android the speech recognition service your phone uses (on most phones Google’s). Swescroll asks Android to recognize speech on the phone when it can, but depending on your phone and whether offline Swedish is installed, the service may process the audio on its provider’s servers. Swescroll compares the text with the sentence and then discards both. Swescroll never saves your recordings or what you said, never sends them to us or to anyone else, and never includes them in usage statistics, which only note that a speaking card was answered and whether it was right. How Apple and Google handle speech recognition is described in their own privacy policies and in the permission prompts your phone shows.

Subscriptions and free trials are processed entirely by Apple on iPhone and by Google Play on Android. We do not receive or store your payment details. If you agreed to usage statistics, they record that a purchase happened (e.g. “trial started”), not who made it.

Study reminders, streak reminders, and trial reminders are local notifications scheduled on your device. No notification data is sent anywhere. On Android, Swescroll also shows an ongoing notification while it is measuring the minutes you earned, because Android requires one; it is created on the phone too.

Swescroll is not directed at children under 13, and we do not knowingly collect data from them.

We rely on your consent for usage statistics, and on our legitimate interest in answering you for feedback you choose to send. You can withdraw consent at any time under Settings → About, without losing any functionality.

Anonymous analytics events are kept in PostHog for as long as they are useful for product decisions and cannot be traced back to you. Feedback you send is kept for as long as it is useful for improving the app; if you gave us an email address, tell us and we will delete both it and your message. Everything else lives on your device — deleting the app deletes it.

Under the GDPR you have rights of access, rectification, and erasure, and the right to lodge a complaint with a supervisory authority (in Sweden, IMY). For anything related to this policy, contact us at info@tinywave.io.

We’ll update this page if our practices change, and note the date above.
