Subprocessors
We use a number of third-party subprocessors (or vendors) to power our app. We share your data with them as outlined in our Privacy Policy.
Here are the vendors we use:
PostHog
Where it is based: USA • We share data from all Users (Children and Adults) • Privacy policy
We use PostHog to monitor how visitors navigate and use our apps so we can spot usage patterns, diagnose UX friction points, and prioritise improvements.
Google Cloud
Where it is based: USA • We share data from all Users (Children and Adults) • Privacy policy
We host our infrastructure on Google Cloud Platform. User data is stored and processed on GCP servers solely so we can deliver the service securely, reliably, and at scale; Google does not use this data for its own purposes.
Sentry
Where it is based: USA • We share data from all Users (Children and Adults) • Privacy policy
Sentry captures real‑time error reports and performance telemetry from our apps. This lets our engineers detect crashes, trace stack traces, and fix issues quickly, improving overall stability.
UpStash
Where it is based: USA • We share data from all Users (Children and Adults) • Privacy policy
UpStash provides a data store for caching, session storage, and event queues. We temporarily store calculated data here to keep the service fast and reliable. Data is deleted after a short period of time.
Meta
Where it is based: USA • We only share data from Adults outside the EU • Privacy policy
For adult, non‑EU visitors we use Meta advertising tools (e.g., Facebook Pixel and Conversions API) to measure campaign performance and serve more relevant ads on Meta services. We transmit hashed identifiers and event data; EU traffic is excluded.
Auth0
Where it is based: EU • We only share data from Adults • Privacy policy
Auth0 provides secure authentication and account‑management. When you sign in, Auth0 processes your credentials and profile attributes to verify your identity, issue tokens, enforce MFA, and protect your account.
Customer.io
Where it is based: USA • We only share data from Adults • Privacy policy
Customer.io sends our transactional and product‑related emails and in‑app messages. We share your email address and usage events so we can deliver messages like confirmations, feature tips, and account notices at the right moment.
