Privacy

Last updated 27 October 2026. Draft.

Short version: no account, no tracking cookies, no advertising. We keep the answers you gave and the plan we built from them, at a private link only you have, and we delete them a year after your race.

What we store

• Your plan and the answers behind it: event, race name and date, age, experience, goal, recent race time, current training, schedule, and anything you write in the notes box. We store these so your plan keeps working and your private link shows how it was built.
• When you gave the health sign-off, stored with the plan.
• Your email address, only if you use Email me this link. It is kept with that plan only to send and resend its links, and goes when the plan is deleted.
• Your answer to "Does this plan look realistic for you?", if you give one, and your optional comment, kept with the plan (with a one-way hash of your IP address so one person counts once) to improve how plans are built.
• A short-lived counter per connection to stop abuse: a one-way hash of your IP address, kept for about an hour. Your IP address itself is not stored with your plan.

We do not need your name, email, sex or weight to build a plan. Please do not put details in the notes box that you would not want stored, or sent to Anthropic as described below.

Your two links

Every plan has two links. Both are long and random, cannot be guessed or looked up, and are kept out of search engines.

• Your private link (it starts /m/) is where you land after building a plan. It shows the plan and your answers, and it is the only way back to change your answers or delete the plan. We cannot find it for you if you lose it, so bookmark it and keep it to yourself.
• The share link (it starts /p/) is what the Share button copies. Anyone with a share link can see the plan: the weeks, paces, assumptions and race day. It does not show your notes, your age, your travel dates or when you gave the health sign-off, and it cannot change or delete anything.

Cookies and analytics

The site sets no cookies for building or viewing plans and runs no advertising or cross-site tracking. The days you tick as done, and whether you have rated a plan, are kept in your own browser's local storage and never sent to us. If we add privacy-friendly visit counts later, this page will say so.

Services we use

• Hosting and email: Hostinger hosts the site and its database, and sends the Email me this link messages.
• Anthropic (Claude): if you write anything in the notes box, its text is sent to Anthropic's API, together with your plan's dates, days and weekly limit, so that Claude can read it into plan constraints (for example "Thursdays off" or "no hard sessions until 15 December"). It is sent once, when the plan is built, and is not used for anything else: not for advertising, not to build a profile of you, and not by us to train any model. Anthropic's commercial terms state that it may not train its models on customer content sent through its API. Your plan lists what was read from your notes, and the share link does not show it. Leave the box empty and nothing is sent.
• Coming soon: Stripe for the optional paid upgrade. This page will be updated before it starts.

How long we keep it

A plan and its answers are deleted automatically 12 months after its race date, or 18 months after it was made if it has no race. You can delete a plan yourself at any time with Delete this plan on its private link; it is removed at once, and both links stop working.

Your rights

Your private link shows everything we hold about your plan, and lets you delete it. You can also ask us to correct or delete a plan, or ask any question about this policy: hello@trainingplanner.app. Send the plan's link so we can find it; we cannot look plans up any other way.
