What we collect: almost nothing.
Google Analytics measures traffic on this site. The waitlist form keeps what you type in it, as one email. That's the whole list.
The short version
Verify it yourself
Don't take our word for it.
Every claim on this page is something you can check in a couple of minutes, in your own browser.
Open DevTools before you paste anything
Run a whole Coverage Check or Expiry Check with the Network tab open. Nothing fires because of what you paste. The Coverage Check does fetch one small, public price list on your first Analyze, and that request carries no trace of your paste. Parsing, matching, and pricing all happen in your browser.
View source on any page
One analytics script, Google Analytics, described below. No ad pixel, no other third-party font or script. The three variable fonts you're reading right now are self-hosted.
Read the Content-Security-Policy header
connect-src allows exactly four destinations: this site, the waitlist form's Lambda function URL, and Google Analytics's two collection domains. Nothing else can receive a request from a page on reserver.io.
What the waitlist form collects
Four fields. One email. No database.
| Field | Why we ask | Where it goes | Retention |
|---|---|---|---|
| Name | So we know who we're emailing back. | One email to the Reserver team | Kept in that email thread until we onboard you or you ask us to delete it. |
| Work email | The only way we contact you about early access. | One email to the Reserver team | Kept in that email thread until we onboard you or you ask us to delete it. |
| Company (optional) | Helps us size your fleet before we reach out. | One email to the Reserver team | Kept in that email thread until we onboard you or you ask us to delete it. |
| Fleet description (optional) | Free text: a rough shape of your AWS setup, or figures carried over from a free tool. | One email to the Reserver team | Kept in that email thread until we onboard you or you ask us to delete it. |
- There is no signup database. The form submits to a Lambda function that sends one email and returns. Nothing is stored on our side beyond that email.
- The function's server logs keep a 90-day retention window, and none of its log lines contains any field you typed, just "signup sent" or an error code.
What the free tools do with what you paste
In your browser, with one bounded exception.
Parsing, matching, and pricing run in your browser
Paste your own aws describe-reserved-* or describe-instances output into Coverage Check or Expiry Check, and every calculation happens on your machine. Nothing you paste is ever sent anywhere.
The one exception, stated plainly
If you choose to carry a tool's result to the waitlist, only the aggregate figures already on your screen travel with it: a coverage percentage, a dollar total, a reservation count. Never a reservation id, ARN, account id, or region. You can read the prefilled text and clear it before you submit.
See it run yourself at Coverage Check orExpiry Check.
Who else touches it
Two sub-processors. That's the entire list.
Amazon Web Services
Hosts the site (S3 + CloudFront), runs the waitlist form's Lambda function, and sends the resulting email through SES.
Runs Google Analytics on this site to measure traffic: page views, referrer, approximate location down to city, device and browser type, and how long you stay. It isn't linked to anything you type into the waitlist form.
Your choices
Ask, and we'll act on it directly.
- Access, correction, or deletion: Ask through the waitlist form and we'll act on it directly. There's no separate account or database record to reconcile.
- We don't sell your information: It isn't for sale, and we don't hand it to a data broker. Reserver runs on the flat price you pay us, not on your data.
- No ad network beyond Google Analytics's own measurement: There's no remarketing tag, no ad pixel, and no ad network script anywhere on this site. We haven't turned on Google Signals or any ads integration for Google Analytics.
Every request goes through the waitlist form. It's the one contact route on this site.
When you connect an AWS account
A read-only role, scoped tight.
What's read
Fleet and reservation metadata (instance classes, regions, engines, terms), plus CloudWatch utilization metrics used to size recommendations.
What's never read
Your workload data. Reserver's read-only role can't read database contents, cache values, or any application data.
The full role scope, including the exact IAM policy, is on the security page.
Changes
This page describes what the site and the waitlist form actually do, read straight from the code and infrastructure that run them. If either one changes (a new sub-processor, a signup database, a different analytics setup) this page gets updated the same day.
Stop overpaying for a steady fleet.
Reserver is in early access. Join the list and we'll onboard you as capacity opens up. Your first recommendation lands within minutes of connecting.
