How to Use CaseStamp

CaseStamp is a personal evidence log: you create a case, add photos and video as things happen, and export everything as a single organized report. This page walks through each part.

Creating a case

Tap New case and give it an Issue title and, if relevant, Who it involves, Where, and First noticed. The Description field is for what happened and what it's costing you — as much or as little detail as you want.

If you're documenting on behalf of an employer, client, or organization, you can also fill in Prepared by, Company / organization, Employee ID, and Title / role. All four are optional, and any that you fill in are printed on every page of the exported report so it's clear who compiled it.

Adding evidence

From inside a case, use Take photo or Record video to capture evidence directly, or add a photo from your library. Every photo and video is stamped the moment it's added with the date, time, GPS location (if location access is granted), and a SHA-256 hash of the file — a unique fingerprint that changes if even one byte of the file is altered later. None of this can be back-dated: the timestamp is set at save time and is never editable anywhere in the app.

Video evidence includes audio. Recording laws vary — some states and countries require everyone's consent before recording audio. Know the rules where you are before recording conversations.

The report

Every case exports as a PDF laid out like a form, not a casual printout — a header block with the case details and preparer information, then each entry numbered in order with its timestamp, GPS coordinates (if available), and SHA-256 hash printed alongside it. That structure is deliberate: it gives whoever receives the report a clear, verifiable chain of custody from the moment each piece of evidence was captured to the moment it was exported.

Sharing a case

The Share action bundles the PDF report together with the case's photos and videos into one share sheet, so you can send everything at once to email, Messages, Drive, or any other app. Email attachments have hard size limits — most providers cap them well under the size a few minutes of video can reach — so CaseStamp keeps the shared package under a size that travels safely by email, and if a video would push the package over that limit, it's left out of the bundle automatically.

A video left out of the bundle is still listed in the report by entry number and SHA-256 hash, so the record of it exists even though the file itself wasn't attached. You can share that video on its own — open it from its entry and use its Share action — to Drive, Messages, AirDrop, or anywhere else that handles larger files, and its hash in the report still verifies it's the same file.

Printing

Print PDF opens your device's system print dialog with the same report document the Share action attaches. From that dialog you can send it to a physical printer, or use your device's own Save as PDF option to get a file without going through Share.

Privacy

Everything above happens entirely on your device. CaseStamp makes no network calls and collects no data — see the Privacy Policy for the full statement. When you share or print a case, you're handing it to an app you chose (Mail, Drive, AirDrop, your printer driver); CaseStamp has no part in, and no visibility into, what happens after that.

Storage

There's no limit on the number of cases you can create. The only ceiling is your device's available storage — and since video files are much larger than photos, video is typically what fills that up first.
