Privacy Policy
Effective 2026-08-06 · version 2
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@wordmiapp.com.
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 identifier, so it is not anonymous. Turning it off stops collection from that point on.
Vocabulary comparison (off by default, opt-in in Settings ▸ Compare with Others). When you turn this on, the app sends how many of your saved words fall into each of five difficulty bands — five numbers — plus an age range if you provide one. It does not send the words. Your numbers join a pool that other opted-in readers are compared against; nobody sees them as yours.
Purchases. Subscriptions are handled by Apple. We receive from Apple whether you have an active entitlement. We never see your payment details.
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 show the comparison you asked for, if you asked for it.
- To honor your purchase.
We do not sell your data. We do not use it for advertising. We do not 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 — only if you opted in — your comparison numbers.
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: retained for up to 24 months, then deleted.
- Your account and words on our servers: kept until you delete your account.
- Comparison numbers: kept while the setting is on. Turning it off deletes them from the pool — the app calls our server and asks for their removal.
5. Your choices and rights
- Turn off usage statistics — Settings ▸ Help Us Improve. Immediate.
- Turn off comparison — Settings ▸ Compare with Others. This also deletes what was already sent.
- Export everything — Settings ▸ Export Data gives you a CSV of your words, tags, and history.
- Delete your account — Settings ▸ Delete Account removes your account and your words from our servers. Deleting the app alone does not do this: your iCloud mirror and your server-side account survive it.
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@wordmiapp.com 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@wordmiapp.com 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.
