Privacy Policy
Effective date: November 1, 2026
Trust Delta Apps (TDアプリ開発室, the "Operator") explains below how it handles information about users of "last-visit" (the "Service") distributed in the United States.
1. Summary
- Without an account, your places, groups and visit records stay on your device. The Operator does not receive or store them.
- An account is needed only for the Monthly Plan (backup, sync and group sharing). Only then are your records stored on the Operator's servers.
- No ads, no analytics, no tracking. The Service shows no ads and does not include third-party analytics or tracking SDKs.
- The Operator does not sell or share your personal information.
2. Information the Service handles
| Category |

| Usage |
Days you used the Service (by day), the surface you used (app), and your plan |

While you use the Service without signing in, the Operator does not record usage. Place searches, address lookups and offline map downloads are counted only as totals, without identifying who made them.
Signing in (Monthly Plan only)
- You sign in with Google or Apple account authentication (the available methods are shown in the app). The Operator does not receive or store your password.
- The Operator requests only what is needed to get your email address. It does not receive your name, profile picture or contacts.
- Your account is identified by the identifier issued by the service you signed in with, not by your email address. Your email address is kept to contact you and for purchases.
- If you choose Hide My Email when signing in with Apple, the Operator receives only Apple's relay address, not your real email address.
- The Operator does not provide your places, visit records, groups or sharing information to Google or Apple.
3. Location information
- The Service does not track your location continuously and never collects it in the background. It gets your device's current location only when you tap "Go to my location" (and, if you turn on the setting to go to your location when the app opens, at that time).
- You can use the Service without allowing location access. You can view the map, add places by choosing them on the map, record visits and use groups without it.
- Coordinates are sent to our place-name provider (Geoapify, Section 5) only in these two cases, through the Operator's server:
- When you open the screen for adding a place — the coordinates of that place, to suggest names and addresses. This happens even if you close the screen without saving.
- When you use "Find places" — the corners and center of the area currently shown on the map, together with the search words or category. Your current location itself is not sent (it is used only on your device to sort results by distance).
- The map itself is delivered by the Operator (through Cloudflare). These requests include the area being shown but are not sent to the place-name provider.
- In all cases, coordinates are not stored in the Operator's database; responses may be cached for a limited time.
4. Technical information
Your IP address is used temporarily to limit repeated requests in a short time. It is not stored in the Operator's database. Our infrastructure provider (Cloudflare) automatically records access logs as part of operating the service.

The Operator does not provide your records, location or other personal information to third parties, except as required by law or when necessary to protect a person's life, body or property.
If you use group sharing, the people you invite can see the data in the shared group (including places, visit records and who recorded them). This is sharing by your own choice.
6. Ads, analytics and cookies
- The Service does not show ads, and the Operator does not provide your data to third parties for advertising.
- The Service does not use third-party analytics or behavioral tracking services (such as Google Analytics) and does not include SDKs or tags for them.
- While you use the Service without signing in, it does not use cookies. When you sign in, the app keeps a sign-in token on your device to keep you signed in; it is not used for analytics or ads.
7. Retention
- Your records without the Monthly Plan: on your device until you delete them or the app. The Operator does not hold copies.
- With the Monthly Plan: account information and records on the Operator's servers are kept until you delete your account (deleted within 30 days; complete removal from backups may take up to 90 days). If your Monthly Plan ends, backups on the Operator's servers are deleted 30 days after it ends; the records on your device remain.
- Usage records (days you used the Service while signed in): 400 days from collection.
- Purchase records: as required by law.
- Messages you send us: as long as needed to respond and to keep a record of the conversation.
8. Your choices and rights
- Export: you can export your data at any time from the app.
- Delete: deleting your records in the app, or deleting the app, removes them from your device. If you have an account, you can delete it in the app (Settings → Account), and your data on the Operator's servers is deleted as described in Section 7.
- Requests: you can contact us at the address below with questions or requests about your information.
9. Children
The Service is not directed to children under 13, and the Operator does not knowingly collect personal information from children under 13.
10. California residents
The Operator does not sell or share personal information (as those terms are defined in the California Consumer Privacy Act) and does not use sensitive personal information to infer characteristics about you. While you use the Service without signing in, the Operator does not keep personal information about you other than the transient technical information described in Section 4 and any messages you send us. If you have an account, you can ask us at the address below to tell you what we hold about you, to correct it, or to delete it.
11. Changes
If we change this Policy, we will announce it in the Service or by other appropriate means. Important changes (such as new purposes of use or new categories of information) will be announced before they take effect.
