Daily OS is a personal reflection app. We collect what you give us — your account info, what you write, and the choices you make in the app — to make the app work and to personalize the AI suggestions you receive. We don't sell your data. You can delete your account anytime.
Daily OS is operated by an individual (referred to as "we" or "us"). For privacy questions, contact: none@domain.com
Account information: your email address and password (which is hashed — we never see the plain text).
Personal context you provide during onboarding: first name, age, relationship context, kids' names, ages, statuses, and optional preferences for how Daily OS refers to your children, work role, faith tradition, growth goals, communication preferences, and any optional context you choose to share. We do not collect your birthday.
Daily entries: the priorities, Your Weather selections and shifts, shift notes, reflections, journal entries, and to-do items you log each day.
A Note You Left records: when this morning ritual is available, we may store the rendered note for your account and local date, the evidence metadata behind it, the prompt version used, and a playback record showing whether that day's note has started or completed. This keeps the note stable for the day and prevents it from replaying across devices.
Accountability partner data: if you use the accountability partners feature, we store the partnership relationship between you and your partner(s), messages sent between partners, and the daily win/loss flag you report each day. See "Accountability partners" below.
Settings: your zip code (so we can show local weather and a small forecast), notification preferences, and display preferences.
Push notification data: if you opt in to browser or device notifications, we store your push token, platform, device/browser label, user agent, time zone, and reminder preferences so Daily OS can send notifications to the right device. You can turn notifications off from Settings.
Technical data: basic usage logs (IP address, browser type, errors) for keeping the app running. We do not use third-party analytics or tracking pixels.
To provide the app: store your entries, show your history, render your dashboard.
To personalize AI output: the personal context you provide, your daily priority, Your Weather, and limited daily context may be sent to Anthropic (the company behind Claude AI) so the AI can generate suggestions specific to you. See "Third-party services" below.
To generate and replay A Note You Left: Daily OS uses your own structured history, selected setup context, and recent rendered note lines to build a morning reflection, keep it consistent for that day, avoid repetitive phrasing, and make sure it only plays once.
To send optional notifications: if you enable notifications, we use your notification preferences, time zone, and push token to deliver reminders and test notifications. Notification payloads are kept brief and should not include journal entries, private reflections, or detailed personal context.
To support you: respond to questions or issues you contact us about.
We do not use your data for advertising, profiling for sale, or training AI models.
The accountability partners feature lets you share a daily check-in with someone you trust. If you use this feature, be aware of the following:
What your partner can see: whether you reported winning or losing the day (your win/loss flag). They do not see your journal entries, to-do items, or other entry content.
What appears in messages: when a partner generates an encouragement message for you, limited context is sent to Anthropic to generate the message text: your first name, today's priority, your win/loss flag (if reported), and your communication preference. Your partner chooses from AI-generated options — they do not write messages from scratch.
Message storage: messages sent between partners are stored in our database and are readable by both the sender and recipient. They are not shared with anyone else.
AI generation: the message generation process sends your first name, today's priority and win/loss status, and your communication preference (e.g., "warm," "direct") to Anthropic. We may compare both partners' faith settings only to decide whether shared faith language belongs in the message. If faith settings do not match, we tell the AI not to use religious or spiritual language. No journal content or detailed personal context is included in partner message generation.
Removing a partnership: either party can remove the partnership at any time from settings. Removing a partnership does not delete historical messages already stored.
Notification when a partnership ends: when you step away from a partnership, the other person sees a brief notification on their dashboard letting them know. You can optionally include a fixed thank-you message. If you instead choose "Remove silently," the partnership ends with no notification — this option exists for safety reasons.
Your Person is an optional mutual connection between two Daily OS users. When linked, each person can see the other's daily priority selection. No other data is shared between linked users — not journal entries, not win/loss status, not reflection content. Priority is the only field that crosses the connection.
Your Person connections require mutual consent. Either party can unlink at any time from Settings. When someone unlinks, the other person receives a brief in-app notification only — no email is sent.
Your Person and accountability partners are separate relationships and cannot overlap.
A Note You Left is a morning reflection that may appear before your dashboard when Daily OS has enough recent history to reflect back. It is assembled from your own structured Daily OS fields, such as priorities, win/loss, Not Today commitments, and Your Weather. It does not quote your journal entries, throw-off reflections, deck items, private partner/person content, or anyone else's private information.
If AI polish is available, the evidence-backed note draft, your feedback style, selected setup context, and recent rendered note lines may be sent to Anthropic so the note reads more naturally. Partner names and children's names are stripped before the AI prompt and are not persisted in the note cache.
We store the rendered note by day so it stays the same for you and so future notes can avoid sounding repetitive. We also store a playback claim for the day so the note starts only once across your devices.
If you submitted a request for early access to Daily OS, we collect your name, email address, and your answers to the request form. This information is used only to evaluate your request and contact you directly. It is never shared with third parties or used for any other purpose.
To run Daily OS, we share data with these providers:
Supabase — hosts our database and handles authentication. Your account info and entries are stored on their infrastructure. Their privacy policy.
Vercel — hosts the website. Standard server logs apply. Their privacy policy.
Anthropic — provides the AI that generates personalized suggestions and accountability partner messages. When Daily OS generates your Daily Word and Lead, your personal context, the day's priority, what you said you won't do, Your Weather, and limited outside weather context may be sent to Anthropic for processing. Child context marked not to be included in prompts is not named in AI prompts. When A Note You Left is polished by AI, the evidence-backed note draft, your feedback style, selected setup context, recent rendered note lines, and structured Daily OS fields such as win/loss, priority, Not Today, and Your Weather may be sent; journal text, throw-off text, deck items, private partner/person content, and cross-user data are not included. When a partner generates a message for you, limited context (your first name, today's priority, win/loss flag, communication preference, and faith matching guidance) is sent to Anthropic. Your weekly summary email is also generated by AI: the past 7 days of your journal entries, win/loss data, threw-off reflections, Your Weather shifts, and shift notes are sent to Anthropic to produce the letter, along with profile context such as age, faith, feedback style, work role, relationship context, child prompt-inclusion settings and optional preferences for how Daily OS refers to your children, growth goals, and current-season context so the letter can use the same guardrails as other Daily OS prompts. Your Person support prompts: when you have an active Your Person connection, we send the following to Anthropic to generate your daily support prompt: your first name, feedback style, relationship context, faith matching guidance, and your person's first name and priority for today. We do not send your person's journal entries, win/loss status, generated Daily Word, generated Lead prompt, Your Weather, or other reflection data. The same data handling rules apply — Anthropic does not train its models on this data per its API terms. Their privacy policy.
Firebase Cloud Messaging — delivers optional push notifications to your browser or device. If you enable notifications, Firebase receives and processes the device push token and delivery metadata needed to send notifications. Firebase privacy and security.
Open-Meteo — provides weather data. We send your zip code's coordinates (no personal info). Their terms.
For A Note You Left specifically, selected setup context may include faith tradition, feedback style, growth goals, current-season context, and whether relationship or children context exists. Partner names and children's names are stripped before the AI prompt and are not persisted in the note cache.
Push notifications are optional. If you enable them, Daily OS stores a device push token and reminder preferences so the app can send reminders or test notifications to that device. Partner thanks and encouragement can also create generic activity notifications; those pushes do not include sender names or message text. You can turn notifications off in Settings, which disables stored device tokens for your account.
Notification content is intended to be brief. We do not put journal entries, detailed personal reflections, or Your Weather shift notes in push notification payloads.
Daily OS sends a weekly summary email every Sunday evening. This email is generated personally for you based on your week's reflection data — your journal entries, win/loss record, what threw you off, and Your Weather shifts or shift notes — plus profile context such as your feedback style, growth goals, current-season context, relationship context, child prompt-inclusion settings, and optional preferences for how Daily OS refers to your children. It is not a newsletter or marketing email.
To opt out, contact us at support@mydailyos.app and we will remove you from the list. We plan to add a one-click unsubscribe link in a future update.
The AI context fields and journal entries can contain personal or sensitive information. We strongly recommend you do not include health information, financial information, or anything you wouldn't want a third party (Anthropic) to process. The AI cannot function without seeing your context, so anything you put in those fields is processed by the AI provider when you generate suggestions.
You can:
Access your data: view it anytime in the app, or contact us for an export.
Correct your data: edit your context, settings, or entries at any time.
Delete your data: delete your account from settings at any time. This permanently removes your account and all associated data within 30 days.
Withdraw consent: you can stop using the app and delete your account at any time.
If you are in the EU, UK, or California, you may have additional rights under GDPR or CCPA. Contact none@domain.com to exercise any of these rights.
We keep your data as long as your account is active. If you delete your account, we remove your data within 30 days. Backup copies may persist for an additional 30 days before being purged. Anthropic may retain logs of API requests separately under their own retention policy (typically 30 days).
Your data is encrypted in transit (HTTPS) and at rest. Passwords are hashed using industry-standard algorithms. Access to the production database is restricted. That said, no system is perfectly secure — if we discover a breach affecting your data, we will notify you promptly.
Daily OS is not intended for users under 13. If you are between 13 and 18, please use this app with the awareness and permission of a parent or guardian. We do not knowingly collect data from children under 13.
We may update this policy. If we make material changes, we'll notify you via email or in-app notice. Continued use of the app after changes means you accept the updated policy.
