Privacy Policy

1. Introduction

StreamArbitrage ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you visit our website at streamarbitrage.com.

2. Information We Collect

You can use the whole site without an account. If you never sign in, we hold nothing about you beyond anonymous analytics.

• Analytics: Vercel Analytics, which collects anonymous page views and does not use cookies or identify you.
• If you sign in with Twitch: your Twitch display name, email address and avatar URL, and the categories you save. Twitch also issues an access token when you sign in, which is stored encrypted and never used to act on your behalf — this site cannot post as you or read your chat. Deleting your account removes it.
• While you are live on Twitch: once you have signed in, we record which category you are streaming, when, how long for, your viewer count and your follower total. This comes from Twitch’s public API, not from your account — it is the same information anyone visiting your channel can see. We use it to verify that a review really came from someone who streamed the game, and to show you what your own hours earned you. Deleting your account removes all of it.
• A session cookie: set only after you sign in, so the site knows it is you. It is HTTP-only, secure, same-site, and expires after seven days. It is not used for tracking or advertising.

3. How We Use Information

Anonymous analytics tell us how the site is used and whether it is working. Nothing more.

Your account signs you in, keeps your saved list, and powers your own dashboard. Your streaming measurements verify that a review came from somebody who actually streamed the game. We do not sell your data, share it, or use it for advertising, and nothing you save is public.

What is public, and this is on by default: the pages for categories you have streamed can show your Twitch display name and avatar, how many hours we measured, your average viewers and how many follows you gained, plus any review you write. Other streamers see the same about you as you see about them — that comparison is the reason the site exists, which is why it starts switched on and why we say so on the sign-in page before you agree to anything. It is all drawn from Twitch’s public API.

Improving the scores: we may use the measurements described above — hours streamed, viewer counts, follower changes, and the category they belong to — in aggregate, to check whether our scoring actually predicts what happens to a streamer, and to improve it. That is statistical work across many accounts, not a profile of you: the output is a better score on a category page, never a judgement about a person. If the numbers show the score is wrong, we change the score. Deleting your account removes your measurements and they are not used in any later analysis; it cannot retroactively unpick work already done, which is why we say this here rather than after the fact.

Turning it off: there is a switch on your account page. It takes effect immediately and everywhere — nothing about your streaming appears on any public page while it is off, and your own dashboard keeps working exactly as before. Your email is never public either way, and neither is anything you save.

4. Third-Party Services

We use the following third-party services:

• Vercel: Hosting and analytics (privacy-focused, no cookies)
• Twitch: public game and streaming data, and — if you choose to sign in — Twitch handles the login itself. We never see your Twitch password.
• Neon: the database that stores accounts and saved lists
• Steam API: Player count data (public data only)
• Ko-fi: Optional donations (handled entirely by Ko-fi)
• Storefronts: We link out to Amazon, Steam, GOG and other shops. Some links may carry an affiliate tag, which tells the shop the visit came from us. We send them nothing about you.

5. Data Retention

If you have an account, we keep it until you delete it. You can do that yourself at any time from your account page. Deleting removes everything attached to you — your details, your saved list, every streaming measurement we have recorded, every review you have written, and your sessions — immediately and for good. We are also required to do this by Twitch’s developer terms if you disconnect this app.

Anonymous analytics are retained by Vercel under their own policy. Data about Twitch categories is not about you and is kept indefinitely.

6. Your Rights (GDPR)

If you are in the European Economic Area or the UK you have rights over your personal data. If you have never signed in we hold none, so there is nothing to exercise them against. If you have an account, you have the right to:

• Access: ask what we hold about you. Most of it is already visible to you on your account and dashboard pages.
• Erasure: delete everything, yourself, from your account page. No request needed and nothing is kept back.
• Rectification: your name and avatar come from Twitch, so changing them there changes them here at your next sign-in.
• Object and restrict: the switch on your account page stops your streaming appearing publicly or being used to improve the scores, without deleting anything.
• Portability: ask and we will send you your data in a machine-readable file.
• Complain: to your national data protection authority, if we have not put something right.

We rely on legitimate interest to publish streaming measurements that Twitch already makes public, which is why the switch exists and why it is described before you sign in rather than afterwards.

7. Children's Privacy

Our service is not directed to children under 13. We do not knowingly collect personal information from children.

8. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
