Privacy Policy

Last updated 10 July 2026

Kaleido is a drawing toy made for children. It has no accounts, no ads, and collects no personal data. We don't know who you are, and we've built it that way on purpose.

The short version. Your drawings stay on your device unless you choose to share them. We collect a small amount of anonymous, cookieless usage information to understand which features people enjoy — with no names, no accounts, no advertising, and no persistent identifier that could follow you or your child across sessions or apps.

Who we are

Kaleido is made by Aran Donohue, an individual developer. If you have any question about privacy, email aran.donohue@gmail.com. This policy covers the Kaleido website (kaleidodraw.app) and the Kaleido apps for iOS and Android, which run the same software.

What we do not collect

No name, email address, phone number, or account of any kind — there is no sign-up.
No advertising, no ad networks, and no advertising identifiers (IDFA/AAID).
No cookies, no browser or device fingerprinting, and no cross-app or cross-site tracking.
No persistent user or device identifier. No session recordings or screen replays.
We never collect, view, upload, or store the drawings you make.

What we do collect (anonymously)

To learn which parts of the toy are fun and to fix problems, the app sends a small stream of anonymous product-usage events. Each event is tagged only with a random identifier that is generated fresh in memory every time the app opens and is never stored — so events cannot be linked to you, to your device, or to a previous session. We also set process_person_profile: false, which instructs our analytics provider not to build any profile of a person.

The events describe interactions with the toy, for example:

that the app was opened, and when the first stroke was drawn;
which features were used — colour, brush size, symmetry slices, mirror/spirograph modes, guides, undo, clear, save/share, opening the About screen;
an anonymous session summary — how long the session lasted, roughly how many strokes were drawn, and the last action before leaving;
basic performance and reliability signals (page-load speed, whether the offline cache installed) and, if the app hits an error, a short error message truncated to 200 characters so we can diagnose crashes;
how you arrived (referrer / campaign tag, e.g. a shared link), and whether the app is installed to the home screen versus opened in a browser.

Approximate location

Like every website, our servers briefly see the IP address your request comes from. We use it only to derive an approximate country (coarse location) for aggregate statistics; it is not stored against these anonymous events and is never used to identify anyone. We do not request or collect GPS or precise location.

Where the data goes

PostHog (product analytics, hosted in the United States) receives the anonymous events above, relayed through our own server so we never rely on third-party cookies. See PostHog's privacy notice at posthog.com/privacy.
Google Firebase Hosting serves the website and app content and keeps standard, short-lived server request logs.

We do not sell data, and we do not share it with advertisers or data brokers — we have none.

Storage on your device

The app stores a little data locally on your device to work well: an offline cache so it runs without a connection (for example on a plane), and — if you're offline — a temporary queue of the anonymous events described above so they can be sent later. This information never leaves your device until it is sent to PostHog as anonymous events, and it contains no personal data.

Children's privacy

Kaleido is designed to be enjoyed by children. Because it collects no personal information from anyone — no accounts, no persistent identifiers, no contact details — it is built to comply with the U.S. Children's Online Privacy Protection Act (COPPA), the UK Age Appropriate Design Code, and the GDPR's protections for children. There is no behavioural advertising and no social features. If you are a parent or guardian and have any question or concern, please contact us at aran.donohue@gmail.com.

Your choices

Because we hold no personal data about you, there is nothing personal to access, correct, or delete. You can stop all analytics at any time by using the app offline (for instance with your device in airplane mode) or by removing the app. If you'd like the aggregate, anonymous data associated with your general use looked into, email us and we'll help however we can.

Changes to this policy

If we change how the app handles data, we'll update this page and its "last updated" date. Meaningful changes will be reflected here before they take effect.
