Privacy Policy

Effective date: July 25, 2026 Last updated: July 25, 2026

This Privacy Policy explains how Truffnet, Inc. ("Truffnet, Inc.," "we," "us," or "our") collects, uses, and shares information in connection with Ink Drake (the "Service"), a service for building and sharing tier lists of book series and for receiving book and series recommendations.

By using the Service, you agree to the collection and use of information in accordance with this Policy. If you do not agree, do not use the Service.

1. Who we are

Ink Drake is operated by Truffnet, Inc.. If you have questions about this Policy or your data, contact us at the address in the Contact section below.

2. Information we collect

We collect personal information as necessary to run the Service. The categories below describe what we may collect depending on how you use it.

2.1 Information you provide

• Account information (if accounts are offered): a username, email address, and password (stored only as a salted hash), or credentials from a third-party sign-in provider.
• Content you create: the tier lists you build, the series you add to them, rankings, titles, and any notes or labels you attach.
• Communications: messages you send us for support, feedback, or bug reports, including their contents.

2.2 Information collected automatically

• Usage data: pages or views you interact with, features you use (e.g., drag/drop actions, exports, recommendation requests), and referring/exit pages.
• Device and connection data: IP address, browser type and version, operating system, screen size, and language settings.
• Cookies and local storage: small data files and browser storage used to keep the app working, remember your in-progress tier list, and understand aggregate usage. See Section 6.

2.3 Information we do not intentionally collect

We do not seek to collect sensitive personal information (such as government IDs, financial account numbers, precise geolocation, health, or biometric data). Please do not submit such information through the Service.

3. The book catalog and recommendations

Ink Drake maintains a catalog of book series and related metadata (titles, authors, cover art, ratings, and similar bibliographic information) sourced from public and third-party sources. This catalog is not personal information about you.

Our recommendation feature is trained on tier-list data. It uses patterns across many users' rankings to suggest series, information you provide us, and information partners provide us to recommend other books and series to you and to other users.

4. How we use information

We use the information we collect to:

• Provide, maintain, and operate the Service, including saving and restoring your tier lists;
• Generate and improve series recommendations;
• Understand how the Service is used and improve its features, performance, and reliability;
• Respond to your support requests and communicate with you about the Service;
• Market to you, including sending you promotional emails, newsletters, and offers about the Service and related products;
• Personalize marketing and advertising, including building profiles from your account, tier lists, and usage data to tailor recommendations, promotions, and ads shown to you on and off the Service;
• Deliver targeted advertising, including retargeting, through third-party advertising platforms and networks (see Sections 6 and 7);
• Detect, prevent, and address abuse, fraud, security incidents, and technical problems;
• Comply with legal obligations and enforce our Terms of Service.

4.1 Marketing communications and your choices

If you receive marketing emails from us, every message includes an unsubscribe link, and you can opt out at any time by using that link or contacting us. Opting out of marketing does not stop transactional or service messages (for example, security notices or account confirmations). Where the law requires your consent before we send marketing, we will obtain it, and you may withdraw it at any time.

5. Legal bases for processing (EEA/UK users)

If you are in the European Economic Area or the United Kingdom, we process your personal data on the following legal bases:

• Performance of a contract — to provide the Service you request;
• Legitimate interests — to operate, secure, and improve the Service, provided these do not override your rights;
• Consent — where required, for example for certain cookies, targeted advertising, or marketing communications (you may withdraw consent at any time);
• Legal obligation — where processing is necessary to comply with the law.

6. Cookies, tracking, and advertising

We and our partners use cookies, browser local storage, pixels, SDKs, and similar technologies to:

• Keep you signed in and remember your session (if accounts are offered);
• Preserve your in-progress tier list between visits;
• Measure aggregate usage so we can improve the Service;
• Understand your interests and activity across sites and over time;
• Deliver, target, and measure advertising, including retargeting you on other websites and platforms, and to share identifiers and activity data with third-party advertising and analytics partners.

Some of these advertising technologies involve "sharing" or "selling" your information as those terms are defined under certain privacy laws. See Section 10 for how to opt out.

You can control cookies through your browser settings, and you can opt out of many interest-based advertising cookies via industry tools such as the Digital Advertising Alliance (optout.aboutads.info) and the Network Advertising Initiative (optout.networkadvertising.org). We also honor the Global Privacy Control (GPC) signal where required. Blocking some cookies or clearing local storage may cause you to lose an unsaved tier list or degrade certain features.

7. How we share information

We share information as described here. Some of this sharing may be considered a "sale" or "sharing" of personal information under laws such as the California Consumer Privacy Act (CCPA/CPRA). You have the right to opt out — see Section 10.

• Service providers: hosting, storage, content delivery, email, and analytics vendors that process data on our behalf under contractual confidentiality and security obligations.
• Advertising and analytics partners: ad networks, exchanges, and platforms (such as major social and search advertising providers) with whom we share identifiers, device and usage data, and profile information to target, deliver, and measure advertising, including retargeting. This sharing may qualify as a "sale" or "share" under applicable law.
• Marketing and business partners / affiliates: partners and affiliated companies with whom we share information for joint marketing, promotions, cross-marketing, and related services.
• Public content: if you choose to share or publish a tier list, its contents (and any username you attach) may be visible to others. Do not include information you want to keep private.
• Legal and safety: when we believe disclosure is required by law, or is necessary to protect the rights, property, or safety of Truffnet, Inc., our users, or the public.
• Business transfers: in connection with a merger, acquisition, financing, or sale of assets, subject to the protections of this Policy.
• Aggregated or de-identified data: information that cannot reasonably be used to identify you, which we may use and share for any purpose, including training and improving recommendations.

We do not knowingly sell or share the personal information of anyone we know to be under 16 without the consent required by law.

8. Data retention

We keep personal information for as long as needed to provide the Service and for the purposes described in this Policy. Account data is retained while your account is active and for a reasonable period afterward. We retain and use de-identified and aggregated data indefinitely. We delete or anonymize personal information when it is no longer needed, subject to legal requirements.

9. Security

We use reasonable technical and organizational measures designed to protect information against unauthorized access, loss, or misuse. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

10. Your rights and choices

Depending on where you live, you may have rights to:

• Access the personal information we hold about you;
• Correct inaccurate information;
• Delete your information;
• Object to or restrict certain processing;
• Port your information to another service;
• Withdraw consent where processing is based on consent.

You also have the right to:

• Opt out of marketing at any time via the unsubscribe link in our emails or by contacting us;
• Opt out of the "sale" or "sharing" of your personal information and of targeted/interest-based advertising. You can do this by using the Do Not Sell or Share My Personal Information link in the site footer, by adjusting cookie settings, or by enabling the Global Privacy Control (GPC) signal in your browser;
• Limit the use of profiling for advertising and marketing where applicable law provides that right.

To exercise these rights, contact us using the details below. We will respond within the time required by applicable law. We will not discriminate against you for exercising your rights.

California residents: you have rights under the California Consumer Privacy Act (CCPA/CPRA), including the right to know, delete, and correct your personal information, and the right to opt out of the "sale" and "sharing" of personal information and of targeted advertising. As described in Sections 6 and 7, we do share and may "sell" personal information for advertising and marketing purposes. You may exercise your opt-out rights using the mechanisms described above.

11. Children's privacy

The Service is not directed to children under 13 (or the minimum age required in your jurisdiction), and we do not knowingly collect personal information from them. If you believe a child has provided us personal information, contact us and we will delete it.

12. International users

We may process and store information in countries other than where you live. Where we transfer personal data internationally, we take steps to ensure appropriate safeguards are in place as required by applicable law.

13. Changes to this Policy

We may update this Policy from time to time. When we do, we will revise the "Last updated" date above and, for material changes, provide additional notice as appropriate. Your continued use of the Service after changes take effect constitutes acceptance of the updated Policy.
