Privacy Policy

Last updated: 2 July 2026

The Thinker (“The Thinker”, “we”, “us”) is a personal planning app operated by Cordelia Kate (Rebellious Business) at mythinker.io. This policy explains what we collect, how we use it, and the choices you have. If you have any questions, email hello@cordeliakate.com.

What we collect

Account details. Your name and email address, handled by our authentication provider (Clerk) when you sign in.
Your content. The things you put into The Thinker: tasks, projects, ideas, rituals, notes, brain dumps and Success Days.
Google Calendar data (only if you connect it). If you choose to connect Google Calendar, we request read-only access to your calendar events.
Billing details. If you subscribe, payments are handled by Stripe. We never see or store your full card details.
Basic usage data. Standard technical information (such as your approximate device and browser) needed to run and secure the service.

How we use Google Calendar data

When you connect Google Calendar, The Thinker requests the read-only calendar scope (calendar.readonly). We use this access for one purpose only: to read your events for the current day so The Thinker can plan your day around your meetings and show you what is coming up.

We do not create, edit or delete anything in your calendar. We do not store your calendar events long-term; they are read when you view your day and are not retained beyond what is needed to show them to you. You can disconnect Google Calendar at any time from the AI Agents settings, which removes our access.

The Thinker’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We do not sell Google user data, we do not use it for advertising, and we do not use it to train generalised AI or machine-learning models.

How your content is used

Your content is used to provide the service to you: to store, organise and display your plans. Some features use AI to help sort your brain dump, build your Success Day or evaluate ideas. To do this, the relevant content is sent to our AI provider (Anthropic) to generate a response. This data is processed to serve your request and is not used to train their models.

Who we share data with

We do not sell your data. We share it only with the service providers that help us run The Thinker, each acting on our instructions:

Clerk for sign-in and account management.
Vercel and Neon for hosting and the database.
Anthropic for the AI features.
Stripe for subscription billing.
Resend for transactional email.
Google for calendar access, only if you connect it.

How we protect and keep your data

Data is stored on reputable cloud infrastructure and access tokens are kept securely. We keep your data for as long as your account is active. You can delete your content in the app, disconnect Google Calendar at any time, or email us to close your account and have your personal data deleted.

Your rights

Depending on where you live (including under UK and EU data protection law), you may have the right to access, correct, export or delete your personal data, and to object to or restrict certain processing. To exercise any of these, email hello@cordeliakate.com and we will help.

Changes to this policy

We may update this policy from time to time. When we do, we will change the date at the top of this page.
