What we collect when you download a companion file
To unlock a companion PDF you provide your email address, an optional name, and the access password from the book. We store:
your email address (lower-cased),
the optional name you entered,
the slug of the file you requested,
your consent flag and the timestamp of the request.
We do not store the access password, payment data, or any tracking identifiers beyond what is technically required to serve the file.
Why we store your email
Delivering the download. Verifying that a real reader requested the file and being able to re-send it if a link fails.
Protecting the materials. Detecting abuse of the access password and enforcing the copyright terms you accepted at the download dialog.
Occasional book updates. Letting you know when the softcover, eBook, or revised companion files become available. You can unsubscribe from any such email with a single click.
Legal basis: Art. 6(1)(a) GDPR (your consent, given via the checkbox in the download dialog) and Art. 6(1)(f) GDPR (our legitimate interest in protecting the copyrighted materials).
How long we keep it
Download records: kept for up to 24 months after your last download, then deleted automatically.
If you unsubscribe from book updates, we remove your email from any mailing use within 30 days and retain only the minimum record needed to honour your opt-out.
If you request deletion (see below), all of the above is erased within 30 days unless a statutory retention obligation applies.
Who can see your data
Your data is stored on our managed database backend inside the EU/EEA and is accessible only to the publisher (2L Advisory Ltd.) and the infrastructure providers strictly needed to operate this site. We do not sell or rent your data, and we do not share it with advertising networks.
Your rights under the GDPR / DSGVO
You have the right to:
access the personal data we hold about you (Art. 15),
have inaccurate data corrected (Art. 16),
have your data deleted (Art. 17 — “right to be forgotten”),
restrict or object to processing (Art. 18 & 21),
receive your data in a portable format (Art. 20),
withdraw consent at any time, without affecting prior lawful processing (Art. 7(3)),
lodge a complaint with a supervisory authority (Art. 77), e.g. the Office of the Information and Data Protection Commissioner in Malta, or your local EU/EEA authority.
How to request deletion
Send a short email from the address you used for the download to privacy@d-big.de with the subject line “DSGVO deletion request”. You do not need to give a reason. We will:
confirm receipt within 72 hours,
erase your records within 30 days, and
send you a written confirmation once deletion is complete.
If you only want to stop receiving book updates but keep your download records, just reply with “unsubscribe” instead.
Cookies & local storage
We aim to use as little client-side storage as possible. We do not embed third-party advertising trackers, social pixels, or cross-site profiling cookies.
Strictly necessary (always on)
dbig.cookie-consent.v1 (local storage) — remembers your choice on the cookie banner so we don't ask again on every visit. Kept until you clear it.
dbig.unlocked.v2 (local storage) — remembers that you successfully entered the book's access password and your email, so companion files unlock without re-prompting. Stored only in your browser; kept until you click “lock again” or clear site data.
Session cookies set by our hosting infrastructure that are required to serve the page securely (e.g. routing, CSRF protection). No tracking purpose.
Legal basis: Art. 6(1)(f) GDPR (legitimate interest in operating the site) and § 25(2) TTDSG (strictly necessary). No consent required.
Optional (only with your consent)
If you click “Accept all” on the banner, we may load lightweight, privacy-respecting analytics in the future (aggregate page-view counts, no cross-site tracking). We do not load any such tools today, and we will not enable them retroactively against an “Essential only” choice.
