Privacy Policy

Effective date: 19 October 2026

This Privacy Policy explains how Tralendr, operated by The Walking Universe ("Tralendr", "we", "our", "us"), collects, uses, shares, and retains your information when you use our website at tralendr.com, our iPhone and Android apps, and our connectors for AI assistants such as Claude, ChatGPT and Gemini (together, the "Service"). It also explains the controls you have over your information. By using the Service you agree to this policy.


1. Information we collect

1.1 Information you provide

1.2 Information collected automatically

1.3 Information from a connected AI assistant

This section is about an assistant you connect sending information to us. For the text Tralendr sends out to language-model providers for its own chat and plan generation, see section 5.2.

If you choose to connect an AI assistant to Tralendr, then when you ask that assistant to create, read, update, or share a trip, it sends us only the information needed to carry out that request, for example a destination, trip dates, place names, and visit times. We do not receive your wider conversation with the assistant, only the specific tool inputs it sends to us. We also store the access tokens that let the assistant act on your account until you disconnect it. See section 5 for details.

1.4 Information from third parties

1.5 Payment information

We do not collect payment information. Tralendr is free, and nothing on it is sold. Where the Service shows travel you could book, booking is not yet switched on; when it is, you will be handed to the travel provider that sells it, who takes any payment under their own terms. Tralendr takes no payment and stores no card details.

1.6 Trips you plan with other people

You can invite other people onto a trip to plan it with you. An invitation is sent to the email address you give us, and the invitation shows who invited them, the name of the trip, and the trip's cover picture. Once somebody is on a trip, the people on it can see each other's name, initials, and the colour we assign them, and can see when another of them has the trip open and which day, and which place on it, they are looking at. We do not show the other people's email addresses, and we do not show anyone where you are — the location your device reports is never shared with the other people on a trip. Anything a person does to the trip — adding a place, moving a day, writing a note — is visible to everyone on that trip and is attributed to them by name.


2. How we use your information (purposes)


3. How we share your information (recipients)

We do not sell your personal information. We share it only as described below.


4. How we retain your information (retention)

We may keep information longer where the law requires it or to resolve disputes and enforce our agreements.


5. AI assistants, and Tralendr's own AI features

5.1 Connecting your own AI assistant

Connecting an AI assistant is optional. When you connect one, you sign in to Tralendr and approve what the assistant is allowed to do, described in plain terms as viewing your trips, creating and editing your trips, and viewing or updating your basic profile. We then issue access tokens that let the assistant act on your account within those limits.

You can see and revoke connected assistants at any time in the Connected apps section of your Tralendr profile. Revoking access takes effect immediately. The assistant itself is run by a separate company, and its handling of your conversation is governed by that company's own privacy policy.

5.2 Tralendr's own chat and plan generation

Tralendr has an assistant of its own. When you ask it a question about a trip, or ask for a plan to be generated, we send the text of that conversation and the facts of the trip — where you are going, the dates or the number of days, the places already on it, and what you asked for — to a language-model provider so that it can answer. The providers we use include Anthropic, OpenAI and Groq; which one answers a given request can change, and we may add or replace a provider without changing this policy.

We do not send your account with it. Your email address, your name, your profile and the other trips on your account are not part of what goes to a provider. If you type something personal into the chat, that text is part of the conversation and goes with it, so treat the chat as you would any message you are sending to a company.

These providers process the text to produce an answer and may handle it within their own terms of service. What each provider keeps, how long it is kept, and how it may be used is governed by that provider's own terms. This is separate from any assistant you connect yourself under 5.1, which is a connection you make and can revoke.


6. Your rights and controls


7. Data security

We use reasonable technical and organisational measures to protect your information, including encryption in transit and scoped, revocable access for connected assistants. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.


8. Children's privacy

The Service is not directed to children under 13, and we do not knowingly collect personal information from them. Where local law sets a higher age of digital consent, that age applies. If you believe a child has provided us information, contact us and we will delete it.


9. International transfers

We operate internationally, and your information may be processed in countries other than your own, including by the service providers listed above. This includes the language-model providers in section 5.2 and our realtime messaging provider, which are based outside the United Kingdom and the European Economic Area or process data there. Where required, we use appropriate safeguards for such transfers.


10. Third-party links

The Service may link to third-party sites and services we do not control. Their privacy practices are governed by their own policies, which we encourage you to review.


11. Changes to this policy

We may update this policy as the Service evolves. We will post the updated version here with a new effective date, and for significant changes we will take reasonable steps to notify you.
