Terms and Conditions

These terms cover the SessionStack mobile app and this website. The short version: it is a free, independent planner built by one person, it is not affiliated with Amazon Web Services, and the official AWS catalogue is always the source of truth for what is on and where. Use it to plan your week, not as a guarantee.

Effective 14 September 2026 · Last updated 14 September 2026

1. Who you are agreeing with

SessionStack is provided by Jim van Eijk, Karperstraat 4, 2421HT Nieuwkoop, The Netherlands, jim@23g.nl. By installing or using the app, or by using this website, you agree to these terms. If you do not agree, do not use it.

2. Not an AWS product

SessionStack is an independent, unofficial planner. It is not affiliated with, endorsed by, sponsored by or connected to Amazon Web Services, Amazon.com, Inc. or its affiliates. AWS and re:Invent are their trademarks, used here only to say which event this plans. Session data is derived from publicly available information about the event and can be incomplete, out of date or wrong. The official AWS re:Invent catalogue decides what is actually on, where and when — always confirm there before you rely on a booking.

3. Your account

You need an account to store a schedule, notes and connections. You are responsible for keeping your password to yourself and for everything done under your account. Give an email address that reaches you, so a reset or a confirmation can get to you. You must be 16 or older to have an account; the app plans a professional conference and is not directed at children.

4. What you may not do

• Scrape, bulk-export or resell the catalogue data, or use the app to build a competing dataset.
• Break into, overload or probe the service, or work around the rate limits and access rules in it.
• Put anything unlawful, abusive or infringing into a display name, a note or a shared block — the parts another person can see.
• Use another attendee's share code without their agreement, or misrepresent who you are to get a connection accepted.
• Reverse engineer, decompile or redistribute the app, except where the law says you may anyway.

5. What you write stays yours

Your schedule, your notes and your evaluations are your content. You keep every right in them. You grant us only the permission needed to run the service: to store them, sync them to your other device, and show them to the connections you have explicitly chosen to share with. We do not publish them, sell them or use them to train anything. What is stored and for how long is set out in the privacy policy.

6. The AI is an assistant, not an authority

Ask turns your sentence into filters, and the planner suggests sessions it believes you can reach in time. Both are best-effort. Walking times, shuttle waits, room capacity and last-minute changes are estimates about a city with sixty thousand other people in it. A suggestion is not a reservation, and a "you can make it" is not a promise. Reserve your seats in the official tooling, and leave when it suits you rather than when the app says so.

7. Free, and provided as is

The app is free to use, and it is provided as is and as available, without warranties of any kind, to the extent the law allows. There is no uptime commitment. The service may change, break, or be discontinued — most likely after the event it plans. We will not lose your data on purpose, but keep an export of anything you would miss: your trip report exports as Markdown from the app.

8. Liability

To the extent permitted by law, we are not liable for indirect or consequential loss, and specifically not for a session you missed, a seat that was gone, a flight you were late for or a decision you made on the strength of a suggestion. Nothing here limits liability for intent, gross negligence, death or personal injury, or any other liability that cannot be excluded under Dutch law. If you are a consumer, your mandatory statutory rights are unaffected.

9. Ending it

You can stop at any time: delete your account in the app under Me → Delete my account, which is immediate and cannot be undone. We may suspend or close an account that breaks section 4, or shut the service down entirely with reasonable notice in the app.

10. Apple and Google

These terms are between you and us, not with Apple or Google. They are not responsible for the app, its content or any support for it, and they give no warranty on it. If the app fails to conform to a warranty, Apple's only obligation is to refund the purchase price, which for a free app is nothing. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you. You confirm you are not in a country subject to a US embargo or on a US prohibited-parties list, and you will follow the usage rules of the store you installed from.

11. Changes

These terms can change. If a change is material you will be told in the app before it applies, and the date at the top says when the current version took effect. Continuing to use the app after that means you accept it.

12. Law and disputes

Dutch law applies, and disputes go to the competent court in The Netherlands, unless mandatory consumer rules in your own country give you a different forum. Before any of that, email jim@23g.nl — nearly everything is solvable that way.
