Privacy Policy

Last updated: July 21, 2026

Ritsuban is a calm daily planner. This policy explains what data we collect when you use it, where that data lives, who processes it on our behalf, and the controls you have over it. The short version: we collect what the product needs to work, we don't sell it or use it for advertising, and you can export or delete everything yourself, in the app, at any time.

1. Data we collect

Account information. When you create an account we collect your email address and, if you sign in with Google, the name associated with your Google account. Authentication is handled by Amazon Cognito (an AWS service). You can sign in with an email address and password or with your Google account; we never see or store your password in our own systems, and Google sign-in shares only your basic profile (email and name) with us.

Your content. The things you put into Ritsuban: tasks and their descriptions, channels, planned days and time estimates, focus-session time logs, weekly-review reflections, and settings such as your timezone.

Email you send to your capture address. Ritsuban gives you a personal email-to-task address. When a message is sent to it, we process the sender address, subject, and message body to create an item in your inbox. The raw email message (including headers and any attachments) is retained for 90 days for reliability and troubleshooting, then automatically and permanently deleted. The parsed subject and body remain as your inbox item or task until you delete them. Treat this address like a password: anyone who has it can add items to your inbox.

Billing information. Payments are handled by payment processors — we never see or store your full card number. Depending on where you subscribe, billing is processed by Stripe (web), Apple (App Store), or Google (Google Play), with RevenueCat managing subscription state across platforms. We store your subscription status (for example: trialing, active, expired) alongside your account.

Technical data. Standard server logs (such as IP address, request time, and user agent) are kept for security and operations. The marketing site and the app do not use advertising trackers or third-party analytics cookies.

2. Where your data lives

Your account and content are stored in Amazon Aurora databases hosted with Amazon Web Services in the us-east-1 (Northern Virginia, USA) region, encrypted at rest and in transit. If you use Ritsuban from outside the United States, your data is transferred to and processed in the United States.

3. How we use your data

  • To provide the product: storing and syncing your tasks and plans across your devices, and turning email you send to your capture address into inbox items.
  • To operate your subscription: trials, billing state, and entitlements.
  • To send service email: things like trial-ending notices, billing-issue notices, and renewal reminders. These are part of operating the service, not marketing.
  • To keep the service secure and reliable: logs, backups, and abuse prevention.

We do not sell your data, share it with advertisers, or use your content to train machine-learning models.

4. Who processes data on our behalf

  • Amazon Web Services — hosting, storage (including Amazon Aurora), authentication (Amazon Cognito), and email delivery.
  • RevenueCat — subscription management across web and mobile.
  • Stripe — payment processing and tax calculation for web subscriptions.
  • Apple and Google — in-app purchase billing on iOS and Android, and Google additionally for optional Google sign-in.
  • Cloudflare — hosting for this marketing website.

Each processor receives only what its role requires (for example, Stripe handles your card; it never sees your tasks).

5. How long we keep it

  • Account data and your content: for as long as your account exists.
  • Raw inbound email (the original message sent to your capture address): 90 days, then deleted automatically.
  • Server logs: kept for a limited operational window, then rotated out.
  • Billing records held by our payment processors are retained according to their policies and legal requirements.

6. Your controls

Export. You can download a complete copy of your data (your tasks, channels, plans, time logs, reflections, and inbox items) from the app's settings, as JSON, at any time.

Deletion. You can delete your account from the app's settings. This permanently removes your account and content from our systems, including your authentication record and subscription profile with our processors. If you subscribed through the App Store or Google Play, deleting your account does not cancel that subscription — cancel it in your store settings, otherwise the store will keep billing you.

Correction and questions. You can edit your content and settings directly in the app. For anything else — including privacy rights requests under the laws that apply to you (such as GDPR or CCPA) — contact us at the address below.

7. Children

Ritsuban is not directed to children and is not intended for anyone under 16. We do not knowingly collect data from children.

8. Changes to this policy

If we make material changes to this policy, we will update this page and note the new date above. For significant changes we will also notify you by email or in the app.
