Privacy Policy

Last updated: November 12, 2026

PocketMoji is provided by Back After Sento. This policy covers the app and pocketjlpt.com. You do not need a PocketMoji account, and we do not show advertising or sell your personal data.

Your practice data

Your study plan, reminder preferences, practice history, confidence scores, and collections are saved on your device. You can export your progress from the app’s Settings. Reminders are local notifications, which you can disable in your device settings. Answer audio uses the Japanese system speech voice.

Optional iCloud sync

When you enable iCloud sync, practice history, collections, and study preferences are mirrored to your private CloudKit database using Apple’s services. Turning sync off stops future sync and keeps local data; it does not delete existing iCloud copies. You can manage the app’s iCloud storage through your Apple account’s device settings.

Usage analytics

The app sends first-party usage events to our Cloudflare service to help us understand and improve onboarding, subscriptions, and practice. These include:

• A random installation identifier, event and session identifiers, event times, and app version and build.
• Onboarding steps and choices, such as JLPT level, learning goals, and reminder decisions.
• Paywall views, selected plans, trial eligibility, and purchase-flow outcomes.
• Practice type, level and lesson identifier, completion, duration, and aggregate answer counts.
• Notification permission status and whether reminders were scheduled or opened.

The installation identifier links events from the same installation. Our analytics database does not store your IP address, name, email address, payment details, individual selected answers, question text, drawings, or collections. The app does not use an advertising identifier or track you across other companies’ apps or websites.

Feedback

If you send feedback in the app, we store your message, optional reply email, random installation identifiers, app version and build, operating-system version, subscription status at submission, and submission time in a private Cloudflare database. We use this information to understand issues and improve PocketMoji, and may link it to analytics from the same installation. We use your email only to reply to you. We delete feedback after one year. You can request earlier deletion by contacting support@backaftersento.com.

Purchases

Apple processes payments and manages subscriptions. The app checks verified subscription entitlements to enable paid content. We do not receive your payment card details. Apple handles purchase information under its Privacy Policy.

Website and service providers

On our homepage, About page, practice, level test, kanji, study-plan, and selected guide pages, we count page views and actions such as level selections, practice starts and completions, level test starts and recommended levels, guide links, media-kit clicks, PDF clicks, plan creation, sharing attempts, and App Store clicks to improve these resources. We record daily totals by page type, JLPT level when relevant, and a referral category such as Google, ChatGPT, Perplexity, Claude, Gemini, direct, a shared link, or a kanji PDF link; we do not store the full referring address, answers, names, schedule values, or an identifier linking events to a visitor. These website totals are retained for 90 days.

A shared study-plan link contains the level and schedule you selected, so anyone with the link can see them.

Cloudflare hosts this website and our analytics service. Network requests necessarily expose connection information, including IP addresses, to the service provider for delivery and security. This website does not set analytics or advertising cookies and does not include third-party marketing trackers. See Cloudflare’s Privacy Policy for its processing practices.

Apple provides App Store purchases and optional iCloud storage. These providers may process information outside your country. If you email support, we use your email address and the information you provide to respond and resolve your request.

Free practice packs and optional email updates

If you request a free practice pack, we collect your email address and chosen JLPT level and immediately show your download link. No email is sent. We store the request, its consent choice and version, and request time in a separate Cloudflare database. Download links expire after 30 days. Expired request records are deleted automatically each day. Connection information is used to limit abusive requests. The kanji list PDFs do not require an email address.

Launch news and occasional free study resources are optional. If you choose them, we save your email, level and consent time separately. These addresses are initially unverified; we do not assume that submitting a form proves ownership of an inbox. Unverified subscriptions are removed automatically after 90 days. If email verification is added later and you confirm, we retain that subscription until you unsubscribe or request deletion. Future marketing emails will include an unsubscribe link.

You can request deletion at support@backaftersento.com. Getting a pack does not require subscribing to updates.

Retention and your choices

Local practice data stays on your device until you remove it or delete the app; device backups and iCloud copies may remain separately. Unsent analytics events older than 29 days are discarded by the app. Received analytics are stored separately and currently have no automatic deletion schedule. We retain them to understand app usage and improve the product, and review deletion requests individually.

You may ask us to access, correct, or delete personal information we hold by emailing support@backaftersento.com. Depending on where you live, you may also have rights to object to or restrict processing, request a copy of your data, or complain to your local privacy authority. Because analytics use a random installation identifier, we may be unable to identify your events from your name or email alone. We will explain what information is needed to handle your request.

Children

PocketMoji is a general-audience study app. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information to us, please contact us so we can investigate and address it.

Changes and contact

We may update this policy as the app changes. The date above shows the latest revision. For questions about privacy, contact Back After Sento at support@backaftersento.com.
