1. what fatcousin is

fatcousin is a personal project by a single independent maintainer. it provides free, browser-based utilities that process files entirely on your device. nothing you put into a fatcousin tool is uploaded, stored, transmitted, or seen by anyone other than you.

the operator has no account system, no telemetry on user content, and no ability to access, recover, or review anything you process here.

2. no warranty

the tools are provided “as is” and “as available”, without warranty of any kind, express or implied — including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, completeness, non-infringement, or uninterrupted operation.

the maintainer does not warrant that any tool will produce correct results, that any tool is suitable for any particular use, or that any output is fit for any specific downstream purpose — including legal, financial, medical, safety, regulatory, or evidentiary use.

3. not professional advice

fatcousin tools are not, and are not a substitute for, professional advice of any kind. this includes — without limitation — legal advice, expert-witness testimony, medical diagnosis, financial guidance, engineering certification, or digital forensic examination by a qualified examiner.

fatcousin forensics is the investigator-facing section of the site (everything under /forensics). tool descriptions inside fatcousin forensics that use the word forensic describe the data domain (file artifacts, logs, metadata) — not a certification, an accreditation, or a guarantee that any output meets the evidentiary standards of any jurisdiction. fatcousin forensics is investigator-grade triage: preliminary, local, and exploratory. every output requires independent verification before any legal use.

4. heuristic and AI-derived outputs

some tools rely on heuristic rules, statistical signals, or machine-learning models. inside fatcousin forensics these are flagged on each tool page with a maturity badge — see the public fatcousin forensics rubric for the grading methodology.

heuristic and AI-derived outputs are hints, not verdicts. they can be wrong. they can be fooled. they can produce false positives or false negatives in ways that are not always obvious. corroborate with independent methods before drawing conclusions.

5. limitation of liability

to the maximum extent permitted by applicable law, in no event will the maintainer be liable for any damages of any kind — direct, indirect, incidental, special, consequential, exemplary, or punitive — arising out of or in connection with the use, inability to use, or output of any fatcousin tool. this includes (but is not limited to) lost profits, lost data, business interruption, professional or reputational harm, or any costs incurred as a result of relying on a tool's output.

some jurisdictions do not allow the exclusion of certain warranties or limitations of liability. in those jurisdictions the exclusions and limitations above apply only to the extent permitted by law.

6. your responsibility

by using fatcousin you confirm that:

• you have the legal authority to process the data you place into any tool — including device data, communications, photographs, audio, business records, and any other input;
• you understand outputs are unverified and require independent corroboration before any consequential use;
• you will not use fatcousin tools for any purpose prohibited by the acceptable-use policy — including stalking, harassment, surveillance, or unauthorized access to systems or accounts;
• you are solely responsible for verifying that any use complies with applicable laws in your jurisdiction.

7. versioning & provenance

every fatcousin tool ships a semver-style version visible in its footer. inside fatcousin forensics, when you capture a tool run into a case session, the version, the tool slug, the input file hashes, the output file hashes, and the local timestamp are recorded immutably in the session's chain-of-custody log. exported .fc-case files preserve this record so a later reviewer can correlate captured outputs with the exact tool engine that produced them. case sessions are a feature of fatcousin forensics and do not apply outside the /forensics section.

8. changes

tool behavior may change without notice as bugs are fixed and methods are improved. the maintainer is not obligated to preserve historical behavior of any tool. if reproducibility matters to your work, capture runs into a case session and preserve the exported .fc-case file.

this disclaimer may be revised; check the version + last-reviewed date at the top of the page. material changes will bump the major version number.
