Marsili Ink / Biblion

Biblion Privacy Policy

Effective date: October 18, 2026.

Biblion is a King James Bible reader published by Marsili Ink, operated by William Perdomo. This page explains what happens to information when you use the app, when you email us for support, and when you visit this website. These are three different things, and they are described separately below.

The short version

The Biblion app has no accounts, no advertising, no analytics and no third-party code (SDKs). Its code contains no network requests.
Your reading position and highlights stay on your device. Marsili Ink does not receive them.
If you email biblion@marsiliink.com, we receive and store that email. See Support emails.
Visiting marsiliink.com is separate from using the app. See This website.

1. The Biblion app

Biblion provides the complete King James Bible for reading on iPhone and iPad. In the current build the app may display its name as “Noösphere Biblion”; this policy applies to that app.

What stays on your device

Biblion stores your reading position, the verses you highlight, and basic app settings in the app’s own storage on your device. Marsili Ink does not receive this information and cannot see it.

What Biblion does not do

It has no accounts or sign-in.
It contains no analytics, advertising, tracking or crash-reporting code, and no third-party SDKs.
Its code contains no network requests, so the app does not send your information anywhere.
It does not use your location, contacts, photos or microphone.
It does not currently synchronize your reading position or highlights between devices.
The initial release has no AI reading assistant or other online service.

Backups and removing your data

Biblion does not run its own backup. Depending on your settings, the regular backups of your device made by Apple (through iCloud or a computer) may include app data; those backups are provided and governed by Apple, not by Marsili Ink.

You can remove an individual highlight inside the app. Removing Biblion from your device removes the app and, under normal iOS behavior, the data stored inside it. Because Marsili Ink never receives this data, there is nothing for us to delete on our side.

Files you choose to import

Some versions of Biblion can import an EPUB file that you select. The file is copied into the app’s storage on your device and is not uploaded by Biblion. If the file is stored in iCloud Drive, iOS may download it to your device using Apple’s services.

Information from Apple

If you have chosen to share crash or usage information with app developers in your device settings, Apple may make aggregate or crash reports available to Marsili Ink through App Store Connect. That reporting is performed by Apple’s systems, not by code inside Biblion, and is governed by Apple’s privacy policy.

The Privacy Policy link in the app

The Privacy Policy link in Biblion opens this page in your web browser. At that point your browser, not the app, contacts marsiliink.com as described in This website.

2. Support emails

You never need to contact us to use Biblion. If you choose to email biblion@marsiliink.com for help or with a question, the following applies.

What we receive

We receive your email address, your name if your email program includes it, the content of your message, any attachments you send, and the technical details that accompany every email, such as the date and time and mail routing information.

How we use it

We use your message to read it, reply to you, look into the problem you describe, and keep a record of the support exchange. We do not sell support emails and we do not use them for targeted advertising.

Where it is handled

Support email is received and stored in Marsili Ink’s email account hosted by Fastmail, a third-party email provider that processes the messages on our behalf. Fastmail’s handling of information is described in Fastmail’s privacy policy.

How long we keep it

We keep support correspondence only as long as is reasonably necessary for customer support, for security, and to meet applicable legal obligations. We have not set a fixed retention period. If we set one, we will state it here.

Please keep it simple

Please do not email passwords, payment details, government identification numbers or health information. Screenshots can reveal more than you intend, so check them before sending.

3. This website

This policy applies to the Biblion pages on marsiliink.com (this page and the support page). The rest of marsiliink.com is a creative studio site that includes a newsletter sign-up and may handle information differently, as described here.

Hosting

marsiliink.com is hosted by Netlify. When you load any page, Netlify receives the technical information your browser sends in order to deliver the page, such as your IP address, the page you requested, your browser and device type, and the time of the request. See Netlify’s privacy policy.

Cookies and analytics

The pages we publish do not include analytics or advertising scripts, and the site’s own code does not set cookies. The two Biblion pages contain no scripts at all.

Fonts

Pages on this site, including the Biblion pages, load their typefaces from Google Fonts, so your browser contacts Google to fetch them. See Google’s privacy policy.

Newsletter sign-up (not part of Biblion)

The MeatHead and Colosseum pages on this site include a newsletter sign-up form provided by Kit. That form, and the email address you enter in it, are separate from the Biblion app and from Biblion support. The Biblion app does not connect to it and the Biblion pages do not include it. If you sign up, Kit processes your email address and may use cookies or similar technology; see Kit’s privacy policy.

Links to other sites

Some pages on this site link to other services, such as X and Instagram. Those services have their own privacy practices.

4. Your choices and requests

Highlights and reading position are on your device, so you control them there. For information we may hold about you, which in practice means support correspondence, you can email biblion@marsiliink.com and ask us:

what support correspondence we hold from your email address; or
to delete that correspondence from Marsili Ink’s email account.

We may ask you to reply from the same email address so we know the request is yours. We will respond as soon as we reasonably can. Deletion remains subject to any legitimate legal or retention requirements that apply. Fastmail, our email provider, may keep copies in its own systems in line with its own policies. Depending on where you live, privacy law may give you additional rights; write to us and we will consider your request.

5. Changes to this policy

If this policy changes, for example because the app gains a feature that handles information differently, we will post the new version at this address and update the dates above.
