Privacy & beta information
MySleepCure online sleep diary · Updated 28 October 2026
This diary is a beta. Automatic backup recovery is not provided for this beta. Export your data regularly from Account → Export all data (JSON), and do not rely on this diary as your only copy. Data may be lost.
Online and printable are different
The printable diary can be completed offline. This online diary stores the entries you choose to save in your account in the cloud. It is for personal reflection and general education, not a diagnostic test or treatment plan.
What is stored and why
Account sign-in uses your email address and password, handled by Supabase Auth. The diary stores your timezone, morning dates, sleep times and estimates, ratings, notes, and any optional habits, sleep aids or custom trackers and answers you enter. It also stores record identifiers, creation/update times and versions, plus your optional email-preference choices and their dates. These support sign-in, saving and editing your diary, trends, exports and preference management. Leave optional fields blank if you do not want to record them.
Services and access
Supabase provides account authentication and stores the diary database. Cloudflare serves this website. Account-confirmation and password-reset emails use the existing authentication email-delivery service. Diary entries are not included in those emails. These providers may process technical information such as IP addresses, request or delivery logs when providing their services. Other diary users are not given access to your records. Authorized service operators may have access when operating or supporting the service. This is not an end-to-end encrypted diary. We have not added third-party advertising or analytics scripts.
Your browser and email choices
The browser stores sign-in/session information so you can remain signed in. Diary drafts and records are not intentionally saved in browser storage by the app. Use your own device and sign out on shared devices. Downloaded exports and printed copies are your responsibility to keep private.
Email tips are optional and do not affect diary access. New accounts have no saved email preference, and the checkbox starts unchecked. Existing saved choices and history are retained. You can explicitly save or withdraw that preference in Account. Saving a preference does not send an email or connect a marketing sender.
Confirmation and password-reset links are verified by Supabase. Expired or already-used links require a fresh request from Account. Some code-based links also require the browser that requested them; email token-hash links do not require that browser information.
Retention, export and deletion
We keep saved entries until you delete them or request account removal. You can edit individual entries, delete them, export saved app data, or choose Delete all diary data in Account. JSON includes your diary and custom answers, trackers, profile and email-preference history; CSV contains diary records. Avoid editing from another tab or device during export: it uses loaded paginated records, not one instant snapshot.
Delete all diary data removes your diary entries, trackers and answers, profile and email-preference history. Deleting diary data does not close your email/sign-in account. To request full account removal, contact mysleepcure@gmail.com from your registered email address. We will verify the request before acting. Do not email your password or private diary entries. Deletion does not necessarily immediately remove provider operational logs or other retained copies; no instant erasure of those copies is promised.
