Privacy

Last updated: 2026-05-04

This site is a free, open-source civic project. It is run by a single individual, not a company. We aim to collect as little data as possible and to be plain about what we do collect.

What we collect

Two kinds of data, both via you actively using the site:

• Bill submissions. When you upload a utility bill, we extract and store: ZIP code, billing period start and end dates, gas usage in CCF, the PGA rate, and the total gas charge. We do not store your name, address, phone number, email, account number, or meter number. Uploaded PDFs are processed and discarded; only the extracted numeric fields are saved.
• A one-way hash of your IP address. When you submit a bill, we compute a one-way hash of your IP and store the hash (not your IP) so we can deduplicate identical submissions. The hash cannot be reversed to recover your IP.

What we do not collect

• Names, addresses, phone numbers, emails (unless you email us — see below).
• Account numbers, meter numbers, or any identifier issued by a utility company.
• Cookies for advertising or third-party tracking. We do not use Google Analytics, Facebook Pixel, or similar.

Analytics

We use Vercel Analytics for basic traffic statistics (page views, country-level location, browser type). Vercel Analytics is privacy-respecting and does not use cookies. No personal data is sent to us or to Vercel.

How we store it

Bill submission data is stored in Supabase (a managed Postgres database) hosted in the United States. We retain submissions indefinitely so the community-data charts can show historical trends. You can request deletion at any time (see below).

How we share it

We do not sell or share submission data with any third party. Aggregated, anonymized statistics — for example, median PGA rates by month, or counts of submissions by ZIP — are displayed publicly on this site. Individual submissions are never shown.

Your rights

Because we don't tie submissions to a personal identifier, we generally cannot match a specific submission back to you. If you remember the date and ZIP code of a bill you submitted and would like it removed, email eli.ackerman@gmail.com with those details and we will delete the record.

Open source

The site's source code is available on GitHub. You can read the exact code that handles your bill submission, including the submit-bill and extract-bill endpoints.

Changes

If we change what we collect or how we use it, we'll update this page and bump the "Last updated" date at the top. Material changes will be announced on the site.
