Privacy Policy
Effective 2026-08-06 · version 1
Wordmi is a vocabulary app. This policy says what it collects, why, who else sees it, and how to make it stop. It describes what the app actually does — if you find something here that does not match the app, that is a bug and we want to hear about it at support@wordmi.app.
1. What we collect
Your account. When you sign in with Apple or Google we receive an account identifier and, if you choose to share them, your email address and name. This is what lets your words follow you to a new device.
Your words. The words you look up and save, the tags you put on them, and when you looked at each one. These are stored on your device and — see §3 — mirrored to your own private iCloud storage.
Usage statistics (on by default, switchable off in Settings ▸ Help Us Improve). Which features you use, which words you look up, add and delete, basic device information, app performance, and crash reports. This is linked to your account. Turning it off stops collection from that point on.
The shape of your vocabulary (sent while Usage statistics are on). Coarse counts of how your saved words spread across our difficulty scale, plus an age range if you choose to give one — counts, not the words. These are stored without your account identifier, so we cannot pick out any particular person's contribution, and for the same reason cannot remove one on request. They feed the app's difficulty features.
Purchases. Subscriptions are handled by Apple. We receive from Apple whether you have an active entitlement; payment details stay with Apple.
We do not collect the contents of anything else you type, your contacts, your location (the bookstore finder asks iOS for nearby results and that search happens on your device), your photos, or your microphone.
2. Why we collect it
- To make the app work — your account and your words.
- To answer lookups the bundled dictionary cannot, by asking our server.
- To understand which features are used and which are broken.
- To honor your purchase.
We do not sell your data, use it for advertising, or build profiles for anyone else.
3. Where it goes
Your device. Your words live in a database on your phone.
Your iCloud. That database is mirrored to your own private iCloud account, using Apple's CloudKit. It is your storage and your Apple account; we cannot read it. This is how your words survive a lost phone, and it happens whether or not you subscribe.
Our servers. Definition lookups the bundled dictionary cannot answer, your account record, and the anonymous vocabulary shapes described above.
Processors we use. These companies handle data on our behalf, under their own privacy policies:
| Service | What it handles |
|---|---|
| Apple (Sign in with Apple, CloudKit, App Store) | Sign-in, your private iCloud mirror, purchases |
| Google (Sign-In, Firebase) | Sign-in, authentication, backend infrastructure |
| PostHog | Usage statistics and crash reports |
4. How long we keep it
- Usage statistics: kept for as long as they are useful for operating and improving the app.
- Your account and words on our servers: kept until you delete your account.
- Vocabulary shape: kept indefinitely, because it is anonymous. Turning off usage statistics stops any further contributions.
5. Your choices and rights
- Turn off usage statistics — Settings ▸ Help Us Improve. Immediate.
- Stop contributing your vocabulary's shape — Settings ▸ Help Us Improve. Immediate. What was already contributed stays, because it is anonymous and there is no way to identify which of it was yours.
- Export everything — Settings ▸ Export Data gives you a CSV of your words, tags, and history.
- Delete your account — Settings ▸ Delete Account submits a deletion request. A person reviews and completes every request, normally within 30 days; it is not instant, and you are signed out as soon as you submit one. You can keep using Wordmi by signing back in before it is processed, or write to support@wordmi.app to cancel a request already sent. Deleting the app alone does not delete your account: your iCloud mirror and your server-side data survive it, and only a completed deletion request removes them.
If you are in the EEA, the UK, or California, you have rights to access, correct, delete, and port your data, and to object to processing. The controls above are how to exercise most of them; for anything else, write to support@wordmi.app and we will respond within 30 days.
6. Children
Wordmi is not directed at children under 13, and we do not knowingly collect data from them. If you believe a child has given us data, write to support@wordmi.app and we will delete it.
7. Where data is processed
We operate in the United States, and our processors may handle data in the United States and elsewhere. If you use Wordmi from outside the US, you are sending your data to it.
8. Security
We use encryption in transit, and access to production data is limited to people who need it. No system is perfectly secure, and we will not pretend otherwise; if we discover a breach affecting you, we will tell you.
9. Changes
We will update this policy as the app changes. The effective date at the top tells you which version you are reading, and material changes will be announced in the app.
10. Contact
Questions, corrections, and requests: support@wordmi.app.
