Frequently asked questions

You can’t. This is by design.

DailyMark is an app for keeping the traces of how you change, designed around the idea of never rewriting the past. Typos and regrets included, records remain as they truly were in that moment.

If you want to delete your entire account, you can do so from “Delete account” in the settings screen. In that case, all records are permanently deleted and cannot be recovered.

* During the trial you get exactly the same features as Pro. After 14 days, unless you cancel, it automatically converts to Pro (¥250/month).

Counting visible characters excluding URLs, the limit is 200 characters in Japanese / 400 in English (it switches based on your device language). Including URLs, the raw length can be up to 1,000 characters.

No. Text only.

Because this app is for keeping what you felt and what you thought, photos, video, location, external links and the like are deliberately left out.

When you pose a question like “What have I been troubled by lately?” or “What was I thinking around this time last year?”, the AI quietly sheds light on your past records and returns a brief sense of patterns and lingering impressions. It does not diagnose, and it does not draw conclusions for you.

AI responses are for reference only and are not medical, legal, financial, or life advice.

Pro unlocks a higher daily limit on records, more monthly questions, the monthly review, and exporting your records.

Yes. When you tap “Go Pro,” the StoreKit dialog shows “14 days free, then ¥250/month” (an Apple Introductory Offer). After 14 days, Apple begins billing automatically. If you cancel during the free period, you won’t be charged (from the App Store subscription management screen).

The trial is once per Apple ID. You can’t use it again with the same Apple ID even on a different device (Apple’s policy; within Family Sharing, only one person can use it).

Yes. Even without linking an Apple ID (“Sign in with Apple” inside the app), you can join Pro through the App Store purchase flow (billed via your iCloud Apple ID). The 14-day free trial and “Restore Purchase” can also be done anonymously.

The only purpose of linking your Apple ID inside the app is to keep using the same records on a different device. It is unrelated to purchasing Pro or the trial.

You can do this through the standard iOS flow.

1. On iPhone, open Settings → your Apple ID name → “Subscriptions”
2. Select “DailyMark Pro”
3. Tap “Cancel Subscription”

You can also open the same screen from “Manage subscription” in the app’s settings. You can keep using Pro features until the next renewal date.

Subscription refunds follow Apple’s refund policy. Please request one through Apple’s “Report a Problem” (reportaproblem.apple.com). As a rule, we do not issue refunds directly.

Pro features (5 records per day, 30 questions per month, the monthly review, and export) become unavailable, but your existing records remain as they are. You can continue to view them on the Free plan.

Yes. The app issues an anonymous ID on first launch, and linking an Apple ID is optional.

However, if you stay anonymous, your records are lost when you change devices or delete the app. If you want to keep them long-term, we recommend linking an Apple ID.

Records that were under your anonymous ID become linked to your Apple ID. If you sign in with the same Apple ID on another device, you can access your existing records.

If you’ve linked an Apple ID, you can carry your records over by completing “Sign in with Apple” using the same Apple ID on the new device. If you stayed anonymous, records are not carried over.

You can do this from “Delete account” in the settings screen. When you choose “Delete” in the confirmation dialog, all records (etched records, marks, and monthly reviews) are permanently deleted. None of it can be recovered.

Even if you sign in again with the same Apple ID after deletion, your pre-deletion data does not return (it is treated as a new account).

The Pro plan offers a “data export” feature. From the settings screen, you can export all your records as JSON or Markdown and, via the share sheet, save them to a file or send them to another app.

• JSON: machine-readable, for future migration to other apps
• Markdown: human-readable, opens in note apps and the like

Export is available up to 3 times per month.

No. The records sent to OpenAI and Anthropic (for generating embeddings and question responses) are guaranteed not to be used for training under each company’s API terms.

No. Each record is restricted so that only its owner can view it, enforced at the database level with RLS (Row Level Security).

See the Privacy Policy for details.

No. Only stack traces and device-type information are sent to Sentry.

iOS 15 or later. Android support is planned for v2.

Things to check, in order:

1. Whether “Receive notifications” is on in the app’s settings
2. Whether iOS Settings → DailyMark → Notifications is set to “Allow”
3. Whether either “Daily reminder” or “Reminder (after a while)” is on
4. Whether the “Daily reminder” time is set to a point later than now

If they still don’t arrive, please contact kokujitsuki@five-birds.com.

Please confirm your OS is iOS 15 or later and update the app to the latest version. If that doesn’t help, contact kokujitsuki@five-birds.com with the symptoms and your iPhone model / iOS version.

Yes. It’s a personal project of five-birds.com (Representative: Masaru Ishimoto).

We aim to reply within 3 business days, but as a one-person project, responses may sometimes be delayed.

In accordance with Article 7 of the Terms of Service, we will give notice via in-app notification at least 30 days in advance. During that period, you can export your records with the Pro feature. After shutdown, all records are permanently deleted.
