DossierDecoder

Who it's for

Privacy-conscious consumers, journalists, and activists who have filed (or are about to file) data-access requests; today they cope by Ctrl+F-ing a 515-page PDF, grepping a Takeout zip, or pasting chunks into a cloud chatbot.

The problem

Time (a weekend of reading per dossier) and legal (you can't tell which third parties received your data or which statute to cite in a deletion demand, so most people give up and file nothing).

How to build it

Local-first desktop app (Tauri) + CLI: drag in the export file, get an HTML/PDF report with page-cited findings, a sortable third-party-recipient table, and mail-ready deletion/opt-out letter drafts; runs fully offline.

How it makes money

Consumers pay $19 per decoded dossier (or $39 for a 5-dossier family pack); they pay because the free options cost a weekend of reading or re-leak the very data they're trying to claw back, while the maintained parsers and legally-cited letter templates are the asset.

Why it doesn't exist yet

DeleteMe/Optery/Incogni monetize recurring broker-removal subscriptions, so a one-time decode product excites no one internally; cloud LLM apps can technically summarize a dossier but uploading your entire data dossier to another cloud AI is a privacy self-own this exact segment refuses. The indie gap: a maintained per-company parser pack plus statute-cited letter templates, updated like adblock filter lists, running fully local.

First users

The commenters on the Wired McDonald's dossier story and r/privacy are literally asking 'how do I read mine' — launch there and on HN timed to the next viral 'my dossier' story, with free decodes for journalists who write those pieces.

Build size

2 people x 10 weeks: parsers for 6 export formats (Google Takeout, Meta Download Your Information, Amazon, TikTok, Apple, generic corporate PDF), local report generator, CCPA/GDPR letter templates; excluded: actually sending or tracking requests, broker opt-out databases, enterprise dashboards.

Biggest risk

A privacy incumbent (Optery/DeleteMe/Incogni) ships a free dossier decoder as a lead magnet, or Apple/Google ship a native 'what they know about you' viewer for their own takeout files, gutting willingness to pay.

Conditions for a hit (all 3 required)

• Given a supported export (Google Takeout zip, Meta DYI zip, or a 100+ page company PDF), outputs a one-page summary naming every data category found and the total count of third parties the document says received the data, each claim page/file-cited.
• Produces a table of named third-party recipients (advertisers, analytics, affiliates) with the stated purpose and legal basis extracted from the document itself.
• Generates ready-to-send deletion/opt-out letters (PDF or email drafts) citing the correct statute per recipient, verifiable by running the whole flow offline with networking disabled.
