Privacy Policy
Last updated: October 30, 2026
This policy explains what Saylore collects, why, and how to control your data. Plain English, no dark patterns.
What we collect
- Account data: email address, display name, password hash (or sign-in provider identifier).
- Learning data: the language and level you're studying, lessons completed, vocabulary you're learning, streak history.
- Conversation & speaking data: messages you send to the AI tutor, transcripts of your speaking practice, and short audio recordings used to score your pronunciation.
- Device data: device model, OS version, app version, language, region, and crash logs.
- Usage data: which screens you open and what you do in the app (for example, a lesson started or finished), linked to a random account ID — never to your email or name — with an approximate location (country and city) worked out from your IP address. It shows us where the app is hard to use.
- The Voice Run game: while you play, your phone's own speech service (Apple's on iPhone, Google's on Android) turns what you say into text — on the device where it can, otherwise on Apple's or Google's servers under their privacy policies. The game checks that text on your phone; neither your voice nor the text is sent to us. In a race with another learner, they see your first name and your level, and your progress in the race (how far you've run, walls passed) goes through our server for that race only: it is kept in memory for a few minutes and never stored. Crystals and supplies stay on your device.
How we use it
- To run the app: keep your progress, sync between devices, and personalise lessons to your level.
- To improve the tutor: aggregate, de-identified data is used to make corrections and explanations better.
- To support you: help us answer your messages when you contact us.
- To process subscriptions: billing is handled by Apple or Google; we receive only the receipt.
What we don't do
- We don't sell your personal data.
- We don't run ads.
- We don't use your private conversations to train third-party AI models.
Who we share it with
A small set of processors that help us run the service — cloud hosting, error monitoring, product analytics, customer support, and the AI providers that power the tutor. Each is bound by a written agreement to handle your data only as we instruct.
Where data lives
Saylore is hosted on cloud infrastructure in the European Union and the United States. We rely on Standard Contractual Clauses for any cross-border transfers.
Your rights
You can access, export, correct, or delete your data at any time. Use Profile → Account inside the app, or email [email protected]. If you're in the EU/EEA, UK, or California, you also have the rights granted by GDPR, UK GDPR, and the CCPA respectively.
Children
Saylore is not directed at children under 13. If you believe a child has provided us with personal data, contact us and we'll delete it.
Changes
If we make material changes, we'll let you know in the app and update the date at the top of this page.
