Privacy Policy
App policy effective September 13, 2026 · Website notice added September 14, 2026
This website
This website is hosted on Cloudflare. Cloudflare processes connection information, such as your IP address and request metadata, to deliver and protect the site. We do not add analytics scripts, advertising trackers, cookies or browser-storage identifiers. There is no sign-up form. Following a store, email or other external link takes you to a service with its own privacy practices. If you email support, the information you choose to include is used to respond to your request. Please do not send confidential work material or recordings.
Workplace Japanese ("the app") is operated by ThinksView ("we"). This policy explains what the app and its online service do with information. Contact: smile@thinksview.com.
The short version
- You can learn without an account. Lessons, progress, review cards and recordings stay on your device.
- Speech recognition runs on your device only. Audio is never uploaded.
- Only if you turn on AI feedback does a reply you confirmed leave your device, to our server and to our AI provider, DeepSeek, which processes it in the People's Republic of China.
- No advertising, no tracking across apps or websites, no analytics SDKs, and we do not sell data.
1. Information that stays on your device
Your practice attempts, progress, review schedule, saved expressions, settings, reminder time and consent receipts are stored locally on your iPhone or iPad. Microphone recordings are kept in temporary storage on the device for replay and removed when the app next starts. Transcripts of your speech are produced on the device. Practice reminders are scheduled by iOS on your device and contain no text you wrote or said. If you use Export learning data, the file is created by you and goes only where you choose to save or share it.
2. AI feedback (optional)
AI feedback is off until you read the in-app disclosure and agree. When you ask for feedback on a reply:
- What is sent: the reply text you confirmed (typed, or transcribed on your device and reviewed by you), whether it was typed or spoken and whether you edited the transcript, and the fictional lesson task it answers. No audio, name, contact details, location or advertising identifier is sent.
- Who processes it: our API, hosted on Cloudflare, and DeepSeek, which generates the feedback. According to DeepSeek's own privacy policy, DeepSeek processes and stores data in the People's Republic of China and may use data to improve its models, subject to the choices its policy describes. See DeepSeek's privacy policy.
- Please do not enter real names, client information or confidential work material. The tasks are fictional and do not need them.
- What we keep: the feedback result for up to 24 hours so a lost connection can retrieve it without charging you twice. After that we keep only a ledger entry — request identifier, a one-way hash of the reply, time and units used — with no reply text.
AI feedback can be wrong. It is labelled as AI-generated and is not a language certification.
3. Anonymous service identity
AI feedback needs to count usage without an account. When you first turn it on, the app creates a key with Apple's App Attest service, which proves the request comes from a genuine copy of the app. We store an identifier of that key as your anonymous service identity and issue a signed session token that the app keeps in the iOS Keychain. It is not linked to your name, Apple ID or email address, and it is not used for tracking.
4. Purchases
Payments are handled entirely by Apple; we never receive card or payment details. To give subscribers their AI allowance, the app sends us the App Store's signed transaction information (such as transaction identifiers, product, purchase and expiry dates). Apple also notifies our server when a subscription renews, expires, is refunded or is revoked, so access follows the real subscription. Purchases made with Apple test (Sandbox) accounts are kept in a separate ledger.
5. Security and abuse prevention
Cloudflare processes your IP address and request metadata to deliver and protect the service. To limit abuse we count requests per address in short windows of up to ten minutes, using a keyed one-way hash of the address rather than the address itself; each counter is overwritten when its window ends.
6. Legal bases
Where laws such as the GDPR apply: AI feedback, and the transfer of your reply to DeepSeek in China, rely on your consent, which you can withdraw at any time. Purchase verification and allowance counting are necessary to provide the subscription you asked for. Abuse prevention and billing records rely on our legitimate interest in a secure, fairly metered service and on legal obligations.
7. International transfers
Our service runs on Cloudflare's global network, and AI feedback is processed by DeepSeek in the People's Republic of China, which may not offer the same level of data protection as your country. By turning on AI feedback you agree to this transfer. If you do not agree, keep AI feedback off — every lesson works without it.
8. How long information is kept
| Information | Kept |
|---|---|
| On-device learning data | Until you delete it in Settings or delete the app |
| AI feedback result | Up to 24 hours |
| Usage ledger (no reply text) | For as long as the service identity or subscription exists, for billing integrity and abuse prevention |
| Consent receipts | Until you delete cloud service data |
| Purchase verification and subscription status | For the life of the subscription and as required for refunds and accounting |
| Rate-limit counters | At most ten minutes |
| Data held by DeepSeek | As described in DeepSeek's privacy policy |
9. Your choices and rights
- Withdraw consent: Settings → AI-generated feedback → Turn off cloud processing. No further replies are sent.
- Delete server data: Settings → Delete cloud service data removes cached results and consent receipts for this device's identity.
- Delete local data: Settings → Delete learning data, or delete the app.
- Get a copy: Settings → Export learning data.
- Depending on where you live you may have rights to access, correct, delete, restrict or object to processing, to data portability, and to complain to a data protection authority. Email smile@thinksview.com; we reply within 30 days. Because there are no accounts, include the approximate time you used AI feedback so we can help without asking for more personal data.
10. Children
The app is designed for adults preparing for or working in Japanese workplaces. It is not directed to children under 16, and children under 16 should not turn on AI feedback.
11. Changes
We will update the version above when this policy changes. If a change affects AI feedback or who processes your data, the app asks for your agreement again before sending anything.
