Reading is private. Here is what we see.

Information we process

• Account information. Your email address, user ID, authentication state, and language preferences when you create or use an account. The iOS app also offers Sign in with Apple; if you choose Hide My Email, we only ever receive Apple’s relay address, never your real one.
• Translation input. Text you select or enter, text recognized from a screen capture, the requested language, and the translation returned to you.
• Saved learning content. Source text, translations, language labels, notes, and timestamps are stored when you choose to save an item.
• Study progress. The iOS app stores the wordbooks you choose to study, your review schedule and results, your chosen memory algorithm, and review timestamps, so progress follows your account across devices.
• Usage records. To account for your subscription allowance, we record how much each AI translation uses and when. Usage records hold amounts only, never the text you translated.
• Purchase records. When you buy a plan, we record the order: plan, billing period, amount and currency, payment method, order status, times of payment and refund, and the transaction, customer, and subscription IDs returned by the payment provider. You enter card numbers, bank details, and Alipay login credentials on the provider’s own checkout page; QuipJot never receives or stores them.
• Technical information. Our infrastructure may generate IP address, request, security, and error records needed to deliver and protect the service. QuipJot does not currently include a third-party analytics or crash-reporting SDK.

Screen capture and macOS permissions

QuipJot requests Accessibility access so it can detect selected text, and Screen Recording access when you use area capture. Captured images are processed locally by macOS Vision OCR and are not uploaded by the current desktop app. The recognized text is then sent for translation. A local diagnostic copy may remain in the macOS temporary directory until it is replaced or the system clears temporary files.

Data that stays on your iPhone

Study reminders in the iOS app are notifications scheduled locally by your phone. QuipJot does not use a push server or collect push tokens. Word and sentence pronunciation is synthesized on the device by the iOS system voice, and no audio is uploaded. Reminder, pronunciation, and haptics settings, along with your answers in past-exam reading, are kept only on your phone and are never uploaded. Deleting the app removes them all.

How we use information

• Authenticate your account and keep your session active.
• Translate text and generate optional vocabulary details.
• Sync content you deliberately save across your devices.
• Process purchases, activate your plan, and handle renewals, refunds, and payment disputes.
• Maintain security, prevent abuse, including repeated claims of one-time offers such as the trial, and diagnose failures.

QuipJot does not sell your personal information or use your translation text for advertising.

Service providers

QuipJot uses Supabase for authentication and saved data, Alibaba Cloud DirectMail to send sign-in code emails, Apple for Sign in with Apple and its private email relay, Render for the translation API, DeepSeek to generate translations and vocabulary details, and Vercel for website and download hosting. Information sent to these providers is subject to their security, processing, and retention practices.

Payments are processed by Alipay for purchases in Chinese yuan and by Stripe for card payments where offered. They collect the payment information needed to complete a transaction, may perform fraud and identity checks, and keep transaction records under their own privacy policies and legal obligations. We receive only the payment result and the identifiers listed above.

Your account information, saved content, study progress, usage records, and purchase records are stored in Supabase’s data center in the eastern United States (Northern Virginia). If you live in mainland China or elsewhere outside the United States, this information is transferred abroad for storage and processing. By using QuipJot, you acknowledge and agree to this arrangement.

Translation text may also be processed outside your country or region. Avoid submitting confidential or highly sensitive text that you do not want an AI provider to process.

Storage and retention

Account details, profile settings, and saved learning content are retained while your account is active or until you delete the relevant saved item. QuipJot’s translation proxy does not write translation content to a database. To return repeated text faster, translations are cached in server memory for up to 24 hours and cleared whenever the service restarts. Infrastructure logs and AI-provider records may be retained under each provider’s policies.

Purchase records are kept while your account exists, so we can show your plan status and handle refunds and disputes.

When you delete your account, we keep a minimal record: a SHA-256 hash of your email address rather than the address itself, when the account was registered and deleted, whether the trial was used, and the purchase records described above. We keep it to meet accounting, tax, refund, and dispute obligations, and to stop one-time offers such as the 7-day trial from being claimed again by deleting and re-registering with the same email. Only our server can read it, it is used for no other purpose, and it is kept for as long as those obligations require. Alipay and Stripe keep their own transaction records independently.

Authentication credentials stored by the desktop app are protected with the operating system’s secure storage when available. Network traffic uses encrypted HTTPS connections. No online service can guarantee absolute security.

Your choices

You can delete individual saved items and sign out from either app. Either app can also permanently delete your account: in the iOS app, use Profile → Account → Delete account; in the macOS app, open the account menu at the bottom of the sidebar and choose Delete account. Deletion removes your account together with your saved items, study plans, review history, and usage records, and the macOS app also clears translations and speaking history cached on that Mac. It is immediate and cannot be undone, and unused paid time is forfeited without a refund. Cancel any Stripe auto-renewal first, and wait for a payment in progress to be confirmed or closed. The minimal record described under Storage and retention is kept.
