Privacy policy

Day Plan is an app for iPhone, iPad, Mac and Apple Watch made by Alex Kerss, who is responsible for your data (the “controller”). This policy explains what Day Plan collects, why, who else handles it, and the choices you have.

• Your Apple sign-in:an anonymous identifier from Sign in with Apple. Day Plan doesn't ask for your name or email address.
• Google Calendar: your events, so Day Plan can draw your day and propose changes. It changes an event only after you approve the change in the app.
• Your Google email address, to show which account is connected.
• What you tell the assistant: your messages, your profile and the notes you save.
• Your subscription: which plan you have and when it renews, from Apple. Apple handles payment; Day Plan never sees your card details.
• Settings and usage: your time zone and language, notification settings, a device token for notifications, and how much of your monthly allowance you have used.

Your voice never leaves your device: speech is turned into text on your iPhone, iPad or Mac. Day Plan does not read your Gmail. If you turn on “Show events from Gmail” in Google Calendar, Google adds bookings to your calendar itself, and Day Plan sees them only as calendar events.

Data is used only to provide Day Plan: to show your day, to plan and propose changes, to make the changes you approve, to send the notifications you ask for, and to manage your subscription and allowance. It is not used for advertising, not sold, not shared for tracking, and not used to train AI models.

Under UK and EU data protection law, Day Plan relies on providing the service you subscribed to (contract), on your consent for sending data to AI models, which the app asks for before the assistant starts, and on legitimate interests for keeping the service secure and working.

To plan your day, the assistant sends your calendar events, your messages to it, your profile and your saved notes to AI models through OpenRouter: DeepSeek's V4.1 Flash, run by hosting companies in the United States, for planning, and TypeSafe's Jev for quick decisions such as sorting event titles into colours. Requests go only to providers that do not keep data for training. The app asks for your permission before any of this happens, and you can read it again in Settings, Privacy and AI.

These companies process data for Day Plan, only to provide the service:

• Railway: hosts Day Plan's server and database.
• OpenRouter, and the AI model hosts it routes to: process requests to the assistant.
• Google: provides your calendar, at your request.
• Apple: sign-in, payments and notifications.

Some of these companies are in the United States. Where data leaves the UK or the European Economic Area, it is protected by the safeguards data protection law requires, such as standard contractual clauses.

• Your profile and saved notes: until you delete them or your account.
• Conversations with the assistant: 90 days.
• Proposed and applied changes, kept so they can be undone: 1 year.
• Purchase records: as long as your account exists, and longer where tax law requires.
• Your Google sign-in token is stored encrypted.
• Calendar events are read from Google when needed and kept only briefly.

You can ask for a copy of your data, ask for it to be corrected or deleted, object to how it is used, or withdraw your consent at any time. Email ops@alexkerss.com. If you are unhappy with how your data is handled, you can complain to the Information Commissioner's Office (ico.org.uk) or your local data protection authority.

Day Plan's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Google data is not used to train general AI models.

In the app, go to Settings, Assistant, Delete account. Everything Day Plan stores about you is deleted straight away, and the Google and Apple sign-ins are revoked. Your calendar keeps the changes you approved. Your subscription is billed by Apple: cancel it in your Apple account settings. You can also remove Day Plan's access to Google at myaccount.google.com/permissions.

Day Plan is not meant for children under 13 and does not knowingly collect their data.

If this policy changes, the date at the top changes too. Important changes are also announced in the app.
