Consumer Health Data Privacy Policy

Effective: October 16, 2026 (previous version effective September 29, 2026)

This policy is for residents of Washington, Nevada, and other US states whose laws protect "consumer health data," including Washington's My Health My Data Act. It explains how Mauve Labs ("we," "us") handles consumer health data in DailyCumulus. It supplements our Privacy Policy.

What consumer health data we collect

Your mood entries may be considered consumer health data because they can reveal information about your mental health. This includes your mood level, feelings, activities, notes, photos, and entry times. The fact that you use DailyCumulus, together with your account details (email, name, sign-in method), purchase records, and crash reports linked to your member ID, may also be treated as consumer health data.

• On the free plan or without an account, we don't collect this data at all. It stays on your phone.
• With Premium, entries dated within your Premium period are stored on our servers so we can back them up and sync them across your devices. This is necessary to provide the cloud backup you asked for.
• Anonymous usage stats (from November 10, 2026 — Privacy Policy, Section 1) contain no mood, feelings, activities, notes, photos, or account details, and use a random install ID that isn't linked to you. We maintain them as de-identified data, we don't attempt to re-identify anyone from them, and we don't let anyone else do so. On iPhone we collect them only if you turn them on in Settings; on Android you can turn them off there.

Where it comes from

From you, when you write entries, sign in, or buy Premium in the app; from your sign-in provider (Google, Naver, Kakao, or Apple) and your app store (Apple or Google) for account and purchase details; and from the app itself when it sends a crash report. We don't infer health information from other data.

How we use it

To store, sync, and show your entries back to you; to manage your account and Premium purchase; and to fix crashes. We don't analyze your entries, and we don't use any of this data for advertising, profiling, research, or AI training.

Sharing and selling

• We don't sell consumer health data, and we don't share it with third parties or affiliates.
• We use processors that handle data on our behalf under contract: Supabase, Inc. (cloud database and file storage; data stored in the Seoul region) and Functional Software, Inc. (Sentry; crash reports, which include your member ID but never your entries).
• We don't allow third parties to collect consumer health data about your activity over time or across other websites or apps.
• We don't use geofencing around health care facilities.

Your rights

You have the right to:

• confirm whether we collect or share your consumer health data, and access it, including a list of any third parties or affiliates it was shared with (there are none);
• withdraw your consent;
• have your consumer health data deleted, including from our processors and backup systems; and
• appeal if we deny your request.

Consent: we collect this data only to provide the backup and features you asked for. You can stop further collection anytime by signing out or deleting your account, and you can turn off crash reports in Settings.

How to use these rights: you can delete your account in the app (Profile > Settings > Delete account), or email mauvelabs@mauvelabsinc.com with the subject "Health data request." Tell us what you'd like us to do and the email address of your DailyCumulus account. We'll verify your request and respond within 45 days (we may extend this once by another 45 days if needed, and we'll tell you if we do). Requests are free up to twice a year.

Appeals: if we deny your request, reply to our decision with the subject "Appeal." We'll respond within 45 days. If you're not satisfied, you can contact your state Attorney General (Washington: atg.wa.gov/file-complaint; Nevada: ag.nv.gov).
