PRIVACY, WITH CARE

Privacy Policy

A clear home for information about your memories. Learn how information is used, stored, shared, and deleted.

Draft for review

This is a draft policy. Operator and provider details will be finalized before publication.

NicoLog Privacy Policy

1. Operator and contact

This policy covers the NicoLog app and related website. The operator's legal name and contact page appear on this site. Use the contact form for privacy questions, and check the reply online with your reference number and secret key. Other services run by the operator have separate policies.

2. Information and purposes

NicoLog uses photos, names and groups, dates, smile scores, moods and notes, optional location information, and facial features registered with consent to record smiles, organize photos, suggest identity matches, create sharing cards, and provide reminders. Smile scores are a guide to recording expressions, not a medical diagnosis or an assessment of mental health. Identity matching may be incorrect and does not verify a person's identity.

3. On-device storage and protection

Photos and records are encrypted in the app's private on-device storage. Keys are handled by the operating system's protected storage. The app does not automatically upload face photos, facial features, or daily records to an operator server. Protection of original photos and exported content depends on the settings of the relevant operating system and service. For inquiries submitted in the app, receipt numbers, secret keys, subjects, dates and the last checked status are kept in protected on-device storage. Checking a reply sends the receipt number, secret key and reCAPTCHA token to nicolog.org over HTTPS. Messages and replies are held only in display memory and are not saved in device history. Receipts are excluded from manual photo backups and automatic sync. Deleting history removes the device receipt; server inquiries follow their separate retention deadline. Numbers and keys are copied only at your request. On iOS, copying excludes transfer to other devices and expires after about one minute.

4. Face analysis and Google ML Kit

Google ML Kit detects faces and processes images on the device. A bundled MobileFaceNet model provides on-device identity suggestions. Google ML Kit may send performance and usage statistics, device and app information, and per-installation identifiers to Google. Google's documentation states that input data such as images and the resulting analysis outputs are not sent to Google servers. Google ML Kit information: https://developers.google.com/ml-kit/terms

5. Sharing, saving images, and backups

When you choose to share, the selected image and displayed information are passed to the destination you select through the operating system. Saving to a photo library or exporting a manual backup is subject to that destination's terms and synchronization settings. The app does not automatically synchronize with an operator server.

6. Retention, deletion, and withdrawing consent

App information is kept until you delete it. You can delete photos and people, reset identity matching in Settings, or delete all in-app data from the privacy screen. Check the relevant screen for the scope of deletion of a person's registered matching features. Deleting in-app data does not delete original photos, exported backups, or images already shared. Delete those separately at their respective destinations.

7. Camera, photo, and notification permissions

The camera is used to take photos; photo access is used to select and save images; notifications provide reminders. You can revoke permissions in your device settings. Features that need a permission may become unavailable. Unnecessary permissions are not forced.

8. Website contact form

We do not collect email addresses or send replies or notifications by email. We store your optional name, app version and OS, inquiry category, subject and message, reference number, published reply and status on the website server for support and troubleshooting. A secret key is shown once after submission; only its verification hash is stored on the server. Anyone with both the reference number and secret key can read the message and reply. Keep both safe and do not share them. Lost secret keys cannot be recovered. Do not include email addresses, photos, facial features, backups or passwords in the message. Access ends at the expiry shown on submission; records are deleted by an hourly cleanup. Replies do not extend this period. Backups and records collected before this change follow their respective retention policies. Connection information is used for short-term anti-abuse limits. Your language preference is stored in this browser. It is not used for advertising or cross-service tracking. The form uses Google reCAPTCHA for spam protection. Choosing “Load reCAPTCHA” connects to Google, which processes IP address, browser, device and interaction information and may use cookies or similar technology. The website server sends the response token to Google for verification, without your inquiry subject, message or secret key. This site does not connect to reCAPTCHA before you load it. Verification is required for new inquiries. Checking an existing reply does not load reCAPTCHA. Google Privacy Policy: https://policies.google.com/privacy Google Terms: https://policies.google.com/terms Add the hosting provider, storage regions and backup retention periods here after contracts are finalized.

9. Third parties, service providers and international handling

The operator does not provide personal information to third parties without consent, except for sharing you request or as permitted or required by applicable law. When website operations use service providers, we review the information entrusted to them and necessary safeguards. Providers and storage regions are listed in section 8. International handling is subject to the explanations and procedures required by applicable law. See section 4 for Google's handling of SDK metrics.

10. Requests about your information

Contact support to request access, correction, deletion or restriction of information submitted through the website. We verify identity only as necessary and respond under applicable law. Do not submit face photos, facial features or device passwords for identity verification. The operator cannot access or delete your on-device photos and records; support can explain the in-app controls.

11. Other people's and children's information

Before registering or sharing other people's photos, personal details or facial matching features, explain the use and obtain necessary consent. Guardians should appropriately manage children's information. Groups organize information on the same device; they do not automatically send it to members or synchronize devices.

12. Updates and questions

We update this page and its revision date when features or information handling changes. Important changes are announced on the website or in the app, and consent is obtained where legally required. Contact support with questions about use or deletion of your information.
