Privacy Policy for Erik Jacobs History Project

What the app does

The app is the functional equivalent of Facebook's Download Your Information for the administrator's own account, performed through the official Graph API. It develops methods for referencing Facebook permalinks reliably inside a personal knowledgebase: resolving a permalink to a stable post identifier, indexing the post, and retrieving it later for historical research. It is a research tool built and operated by one person, the app's administrator, Erik Jacobs.

What data is accessed

The app is currently in development mode and is used solely by its administrator, Erik Jacobs. It builds a personal archive of the administrator's own Facebook timeline through the official Graph API, using his own login: his posts (permalinks, post IDs, timestamps, and text) and the public comments on those posts.

Because a timeline archive naturally includes the public replies others chose to post there, the archive also contains the names and comment text of other Facebook users who commented publicly on the administrator's posts. Reaction totals are stored as aggregate counts only — the API does not identify who reacted.

The app does not access other users' timelines, private messages, groups, or friends lists — only the administrator's own timeline.

How the data is used

The data is used solely to test and refine methods for referencing, indexing, and retrieving the administrator's own public history content for personal archival purposes. It is not used for analytics, advertising, profiling, or any commercial purpose, and it is not used to train machine-learning models.

Where the data goes, and for how long

Data retrieved by the app, including comments others posted publicly on the administrator's timeline, is stored as part of that archive on hardware the administrator controls. It is never shared, sold, or disclosed to any third party. It is retained only as long as it is needed for development of the knowledgebase, and is deleted when it is no longer needed for that purpose.

Data deletion instructions

Anyone who wants their own comments removed from the archive, or any other data associated with this app deleted, can request it in either of these ways. Requests are honored within 30 days.

1. By email. Send a request to erik.jacobs@gmail.com with the subject line "Data Deletion Request - Erik Jacobs History Project" and include the permalink or a description of the content. The data will be deleted within 30 days, and you will receive a confirmation by reply.
2. Through Facebook. Open Facebook Settings & Privacy → Settings → Apps and Websites, find Erik Jacobs History Project, and choose Remove. Removing the app revokes its access; a deletion request sent through that flow is honored on the same 30-day schedule.

If the app ever expands beyond the administrator's own timeline, this policy will be updated first and the app will be submitted for Facebook App Review before any such access begins.

grettir.ai collects nothing

The rest of grettir.ai is a static demonstration site for the open-source Editorial Council project. It has no accounts, no upload forms, no analytics, no advertising, and sets no cookies of its own. The site is served through Render and Cloudflare, whose servers keep ordinary access logs (IP address, requested page, user agent) for operational purposes under their own privacy policies; the site operator does not use those logs to identify or track visitors.

Terms of use for the app and this site

The Erik Jacobs History Project is a personal, non-commercial research application. It is in development, is operated for the sole use of its administrator, and is not offered to the public as a service. The app and this website are provided "as is," without warranty of any kind, and the operator accepts no liability arising from their use. The Facebook data the app touches remains subject to Facebook's own Terms of Service and Platform Terms. These terms and this policy are governed by the laws of the State of California, United States.

Changes to this policy

This policy may be updated as the project develops. The effective date at the top of the page will change whenever it does, and the current version is always the one published at grettir.ai/privacy.
