Privacy Policy

LastEmber · Effective date: June 25, 2026 · Last updated: July 9, 2026

LastEmber ("LastEmber," "we," "us," or "our") is a minimalist Moment-preservation app that lets people leave one carefully chosen Moment in the world every few days, and receive quiet emotional resonance from strangers. This Privacy Policy explains what information we collect, how we use it, and the choices you have. By using LastEmber, you agree to the practices described here.

Controller / operator: Hengtong Li (李恒通), operator of LastEmber.
Contact: hengtong.li@foxmail.com
If a local representative or data-protection officer becomes legally required for a specific launch region, we will publish that representative's contact details before launch in that region.

1. Information We Collect

1.1 Account Information

LastEmber uses Sign in with Apple exclusively. We do not support email/password registration, and we do not request your name, email address, phone number, or contacts. Apple provides us with a stable, anonymous identifier for your account; we do not receive or store your real Apple ID email unless you explicitly choose to share it through Apple's relay service, and even then we do not use it for marketing.

1.2 Content You Create

When you publish a "Moment," we store:

1.3 Location Information (Optional, Coarse Only)

If you enable location access, LastEmber records only a city-level, coarse location when you publish a Moment — never your precise GPS coordinates, and never your real-time location while browsing. If location is enabled, any coordinate used for place-based visualization is further obfuscated with a random offset of 2–5 km around your city center before being stored. You can use LastEmber fully with location access turned off; this only disables city context and related place features for your Moments.

1.4 Usage and Interaction Data

We record limited interaction signals required to operate the app's core mechanics:

We do not sell your personal information, and we do not use your content or coarse location for targeted advertising.

3. Content Moderation & Safety Processing

To keep LastEmber safe, every post is automatically screened by an AI-based content safety filter (for spam, links, contact information, QR codes, and clearly harmful content) before it can be distributed publicly. We also operate a reporting and blocking system: reports are reviewed by automated systems and, where necessary, human moderators within 24 hours. See our Community Guidelines for details.

4. Data Storage, Backend, and Security

5. Data Retention

6. Your Choices and Rights

Depending on your region, you may have additional rights. To exercise these rights, contact us using the details below. We may need to verify that the request comes from the account holder before acting on it.

6.1 EEA / UK / Switzerland

Where GDPR, UK GDPR, or similar law applies, you may have the right to request access, rectification, erasure, restriction, portability, objection to processing based on legitimate interests, and withdrawal of consent for optional features. You may also lodge a complaint with your local data protection authority. We do not use your data for solely automated decisions that produce legal or similarly significant effects.

6.2 California and other U.S. state privacy rights

We do not sell personal information and do not share it for cross-context behavioral advertising. We do not use sensitive personal information to infer characteristics about you. Depending on your state, you may have rights to know, access, delete, correct, obtain a portable copy of, or appeal a decision about your personal information. You may use an authorized agent where applicable law allows it, subject to verification.

6.3 Australia and New Zealand

You may request access to or correction of personal information we hold about you. You may also contact us to complain about how we handle personal information; we will review and respond within a reasonable time. If unresolved, you may contact your local privacy regulator, such as the Office of the Australian Information Commissioner or the Office of the Privacy Commissioner in New Zealand.

7. Children's Privacy

LastEmber is not directed at children under 13 (or the minimum age required by your country of residence). If your country requires a higher age for digital consent, you must meet that higher age or use the App only with valid parental/guardian consent. We do not knowingly collect personal information from children. If you believe a child has used LastEmber to create an account, please contact us so we can remove the associated data.

8. International Data Transfers

LastEmber is available worldwide, and your data may be processed on servers located outside your country of residence, including through Apple and Google/Firebase infrastructure. Where required, we rely on adequacy decisions, standard contractual clauses, data-processing agreements, or comparable safeguards provided by our infrastructure providers to protect data transferred internationally.
