Privacy Policy
This document was last updated October 14, 2026. We recommend reviewing it periodically.
1 · What we collect
We collect only what you give us:
- Account information: your email address and password (password is hashed — we cannot see it).
- Case data: the entries you record, the photos, documents and recordings you add, the people you name, the messages you paste in or email to a case, and any amounts you enter.
- Error reports: if a page breaks, a short report goes to Sentry: the type of error, where in our code it happened, and the page address (with anything after the
?removed). It contains nothing from your cases, nothing you typed, no cookies and no account details.
2 · How we store your data
Your data is stored in Supabase, a secure cloud database hosted in the United States (US East region). Each user's data is isolated using row-level security — no other user can see or access your records. It is encrypted in transit and at rest by our hosting providers, who hold the keys. It is not end-to-end encrypted: our service can read it in order to run it.
Photos and documents are stored in Supabase Storage. A link that opens one expires within an hour. That includes the attachments of a message you email to your case, which are kept when the message is filed, up to 10 MB a file — larger files, videos, programs and archives are listed rather than kept. A message from an address that is not on your case keeps no files at all, only a list of them. Files are only accessible to the account whose case they belong to.
3 · Who can access your data
No other account can reach your data — the database refuses it. Our own servers read it only to do the jobs this policy describes: filing mail you send to your case, building your case file, the daily backup, and the schedule in section 7. There is no screen in the product that lets anyone at BuildMyEvidence open your case.
We will not open your case unless you ask us to for support, or the law compels us.
We will never sell, rent, or share your personal data with third parties for marketing purposes.
4 · Service providers
We use the following third-party services to operate buildmyevidence:
- Supabase — database and file storage (US East)
- Vercel — web hosting and serverless functions
- Cloudflare — DNS, email routing, security, and encrypted backups
- Stripe — payment processing
- Resend — email delivery for account notices
- Sentry — error alerts when a page breaks (United States)
- GitHub — runs the daily backup job
Each provider has their own privacy policy.
5 · Cookies
We use cookies only for authentication (keeping you signed in). We do not use tracking cookies, advertising cookies, or third-party analytics cookies.
6 · Your rights
You have the right to:
- Access all of your data at any time through the app
- Take everything out, with "Take everything out" on your account page
- Delete the items and files you added, or whole cases
- Delete your account entirely, from your account page
- Request a copy of all data we hold about you
7 · How long we keep things, and who else touches them
7.1 Your cases stay until you remove them, or the account goes
We don't put an expiry date on your records. A case stays for as long as the account it lives in stays.
An account ends only through going unused. A free account that hasn't been signed into or used for 12 months is closed, and its records are deleted. We email you 30 days and 7 days before, with a link to take everything out. Signing in keeps it open. An account with a paid case is never closed for going unused. If either email cannot be sent, nothing is closed. The full wording is in section 6 of the Terms, and it means the same thing there as it does here.
7.2 What we actually remove
When an account is deleted, the records go and the files you uploaded go with them, out of storage. It isn't a flag on a row that hides things from you while we keep them.
Before any of that, you can take everything out — free, at any time. The files come out as they reached us, with one exception: a JPEG photograph's location data is removed — on your device for a photo you add yourself, and by us as soon as an emailed one arrives, before it is fingerprinted and kept. A HEIC photo is kept exactly as it arrived, and the app marks it as not checked for location.
7.3 When you delete a case yourself
It goes when you press the button. There is no waiting period and no recycle bin. The copies that outlive the button are the backups §7.4 describes.
The files go out of storage first, then the records that point to them — that order, because doing it the other way would strand your files somewhere nothing could ever reach them again. Afterwards we look in the storage again and check that what should be gone is gone, rather than taking the first answer on trust.
Closing a case is a different thing entirely, and it removes nothing. A closed case is simply one you've finished with. There's no clock on it.
7.4 Backups, and how long a deleted thing stays in one
Every day a job we run on GitHub copies the records and the files and sends the copy to Cloudflare, in the United States. It is encrypted on the machine that makes it, before it is sent, and Cloudflare cannot read it. The key that opens it is not on the machine that makes the backup and not with the company that stores it.
After you delete something, it can remain in those encrypted backups for up to seven days. Each day the job runs, it deletes the backups older than seven days.
Separately, Supabase keeps its own backups of the database, on its own schedule. We cannot search those, and we cannot delete from them.
7.5 Who else handles your information
Running BuildMyEvidence means using a small number of other companies. These are all of them, and what each one holds:
- Supabase
- The database and the file storage. Your cases and the files you upload physically sit here.
- Vercel
- Serves the site and the app to your browser. Handles the request, not the contents of your case.
- Cloudflare
- Sits in front of the site, filtering traffic and blocking abuse, and holds the encrypted backups.
- Stripe
- Takes payments for case file downloads. Your card details go to Stripe and never reach BuildMyEvidence. Stripe never sees what the case is about.
- GitHub
- Runs the daily backup job. The job reads your records and files onto a GitHub machine and encrypts them there before they are sent to Cloudflare.
- Resend
- Sends the emails we have to send you — including the notices described in section 6 of the Terms. Resend receives your email address and the wording of the message. It never receives anything from inside a case, and we don't use it to send you anything you didn't ask for.
- Sentry
- Tells us when a page breaks. It receives the type of error, where it happened in our code and the page address. It never receives anything from inside a case, your email address or anything you typed, and it is set not to store your IP address.
Those are the only companies that hold or handle anything from your account. We don't sell your information, we don't use it for advertising, and nothing in your case is used to train anything. We count visits to our public pages, like the home page and guides, with Vercel Web Analytics. It uses no cookies and doesn't identify you. There is no third-party analytics or tracking inside the app: nothing in your account or your cases is ever sent to an analytics service. We count, anonymously, how many cases reach each step (started, first entry, price shown, paid) and which link they came from, as a short tag such as "reddit". Nothing you type is part of it, and the count holds no account or case details.
Nothing in your case is sent to any AI service. Not by us, and not in the background. If you choose to take your own record to an AI yourself, that is you doing it, in your own account with that company.
7.6 Recordings
If you record audio into a case, the recording is a file like any other file. It is stored, and it is not transcribed. No audio is sent anywhere to be turned into text.
8 · Children
buildmyevidence is not intended for use by anyone under 18 years of age. We do not knowingly collect data from minors.
9 · Changes to this policy
We may update this policy from time to time. Significant changes will be communicated by email or through the app.
