Welcome to Stck!

Stck (stck.me) is a publishing and reading platform. Creators use Stck to write and publish stories, chat-fiction, and books; readers use Stck to read, collect, and buy them. This Privacy Policy explains how we collect, use, disclose, and protect information when you use Stck’s services, including stck.me, Stck Books (our print-on-demand and global publisher distribution service), and Whisper (our AI character chat product). Capitalized terms not defined here have the meaning given to them in our Terms of Use. If you do not agree with this Privacy Policy, you should not use the Service.

1. Information we collect and its use

(a) Information you provide us directly

We collect information such as your username, first and last name, birthdate, phone number, profession, and email address when you register for a Stck account or correspond with us. We also collect:

  • Any messages you send us, and Content you post to the Service — text, images, audio, video, or manuscripts you upload to your stories, comments, or Stck Books catalogue.

  • Publisher and creator account information. If you’re a publisher, author, or imprint distributing through Stck Books, we collect business details (company name, registered address, tax identifiers), catalogue metadata (ONIX records), and payout information needed to pay you for sales — see 1(j) below.

  • Shipping information. If you order a physical, print-on-demand book, we collect the shipping address, and share it with our POD and fulfillment partners to produce and deliver your order.

We use this information to operate and maintain the Service, correspond with you, process your orders or payouts, and address issues you raise.

(b) Information we receive from third parties

If you sign in to Stck through a third-party account (such as Google), that provider will share limited account information with us — for example, your name, email address, and a unique identifier — so we can create or log you into your Stck account. You can review and adjust what’s shared via that third party’s own privacy settings, and you can unlink your account from Stck at any time in your account settings.

(c) Information we collect from you automatically

We use analytics tools to measure traffic and usage trends on the Service — for example, which pages and stories are viewed, and how people navigate the site — so we can improve it. See our Cookies Policy for details and opt-out information.

(d) Cookies and similar technologies

We use cookies to keep you logged in, remember your preferences, and understand how the Service is used. You can control cookies through your browser settings; disabling them may affect some Service features. See our Cookies Policy for more detail.

(e) Log file information

Our servers automatically record log information such as your IP address, browser type, referring/exit pages, and how you interact with links on the Service.

(f) Device identifiers

If you access the Service through a mobile app, we may collect device identifiers (such as a UUID) to recognize your device and keep you logged in.

(g) Location data

If you add a location to your profile, or if we infer an approximate location from your IP address, we use this to offer localized content (for example, currency, shipping options, or regionally relevant catalogues).

(h) Content and activity data

We use your activity on the Service — stories you read, collections you create, comments you write — to recommend content and improve the Service. For example, if you read and collect science-fiction serials, we may recommend similar stories.

(i) Whisper — AI chat conversations

Whisper lets you chat with AI-driven characters from serial fiction. When you use Whisper:

  • Your messages, and the AI’s responses, are stored so the conversation can continue and so you can revisit past chats.

  • Your messages are processed by third-party AI model providers in order to generate responses. We do not permit these providers to use your conversations to train their own models beyond what’s needed to provide the service, and we require them to handle your data under contractual data-protection terms.

  • Whisper conversations are not shared publicly and are not visible to other users, unless you explicitly choose to share an excerpt.

(j) Payment and payout information

  • Payments from readers/buyers. Stck uses third-party payment processors to process purchases, and for certain transactions a payment processor acts as Merchant of Record. We do not store your full card number; our payment processor(s) handle that directly under their own privacy policies and PCI-DSS obligations.

  • Payouts to creators and publishers. If you earn revenue through Stck (story sales, book royalties, or Stck Books distribution fees), we collect the information needed to pay you — such as bank account details and tax identification — and share it with our payment/payout processor to complete the transfer. We do not store full bank account numbers ourselves beyond what’s needed for reconciliation.

2. How we use your information

We use the information we collect to:

  • Provide the Service — operating your account, publishing your Content, fulfilling print and digital orders, and processing payouts to creators and publishers.

  • For data analytics — improving the Service and understanding aggregate usage patterns.

  • Customize the Service for you — for example, recommending stories or chapters based on your reading activity.

  • Communicate with you — technical notices, security alerts, order confirmations, and administrative messages.

  • Promote and drive engagement — telling you about new features, Whisper series, or Stck Books catalogue additions you may be interested in. You can opt out of these as described in Section 8.

  • Customer support — resolving issues you raise and improving the Service based on them.

  • Security — monitoring for suspicious or fraudulent activity and enforcing our Terms of Use.

  • Legal compliance — complying with law, enforcement requests, and protecting the rights, property, or safety of Stck, our users, or others.

  • Where you’ve given consent — for any purpose you’ve specifically agreed to, which you may withdraw at any time.

Legal bases for processing under the GDPR (for users in the EEA/UK)

If you’re accessing Stck from the EEA or UK, we process your personal data where:

(i) it’s necessary to provide the Service to you; (ii) it’s in our legitimate interests (e.g. improving the Service, preventing fraud); (iii) you’ve given consent; or (iv) it’s necessary to comply with our legal obligations.

You can withdraw consent at any time by emailing community@stck.me or via your account settings. Where we rely on legitimate interest, you have the right to object.

3. Sharing your information

We don’t sell or rent your information to third parties outside Stck and its group companies without your consent, except as described below.

(a) Service providers

We share information with third parties who help us run the Service, including:

  • Payment processing and payouts;

  • Print-on-demand and fulfillment partners;

  • AI model providers, for Whisper conversations (see 1(i));

  • Customer support and account management;

  • Email and communications services;

  • Hosting, storage, and infrastructure;

  • Analytics.

These providers only get the information they need to do their job, and are contractually bound to protect it and use it only for that purpose.

(b) Content you choose to share

Stories and books you publish become visible to the public, subject to your privacy settings. If you remove published Content, copies may remain in cached pages or if other users have already saved them. You may also choose to share your Stck stories to social platforms; their own privacy policies apply once shared there.

(c) Sharing with publishers and distribution partners

If you publish through Stck Books, your catalogue metadata and relevant author/publisher business information is shared with our distribution partners (for example, HarperCollins India, IPG, Author Solutions, and regional POD/distribution partners) as needed to list, print, and distribute your books.

(d) Other circumstances

We may also share information where required by law or legal process; to protect against fraud or investigate misuse; where you’ve consented; or if you install a third-party app that connects to Stck (which is then governed by that app’s own privacy policy).

If Stck is acquired, merged, or its assets sold, your information may be transferred as part of that transaction; we’ll notify you by email and/or a notice on the Service.

We may share aggregated, anonymized data (stripped of anything identifying) with partners or the public — for example, industry benchmarking with publishers.

4. How we transfer, store, and protect your data

Your information is stored and processed in the United States, and other countries where Stck or its service providers operate. By using the Service, you understand your information may be transferred to and processed in a country whose data protection laws differ from your own.

5. Cross-border transfers (for users in the EEA/UK)

Where we transfer your information to a provider outside the EEA/UK not covered by an adequacy decision, we require appropriate safeguards, such as the EU Standard Contractual Clauses.

6. Keeping your information safe

We use reasonable technical and organizational measures to protect your information — including requiring a unique password to access your account. No method of transmission or storage is 100% secure, and we can’t guarantee absolute security. You’re responsible for keeping your account credentials confidential.

7. Data breach notification

If information under our control is compromised in a security breach, we’ll investigate and, where appropriate, notify affected users and relevant authorities in accordance with applicable law.

8. Your choices about your information

Account settings. You can update your account information anytime by logging in and editing your profile. You can unsubscribe from promotional emails via the link in those emails. You cannot opt out of Service-related emails (billing, security, order confirmations) but can object by emailing community@stck.me.

Cookies. Adjust your cookie settings via your browser. See our Cookies Policy.

EEA/UK rights. You can request a copy of your data, correction of inaccuracies, deletion or restriction, a portable copy, or object to our processing — email community@stck.me. We may be unable to fulfil some requests (e.g. where it would infringe another user’s rights, or where we’re legally required to retain the data).

Whisper conversation deletion. You can delete individual Whisper conversation histories from your account settings; deletion removes them from our systems within 30 days.

9. How long we keep your information

We retain your profile information and Content for as long as you have an account, and for a commercially reasonable period after, to comply with legal/audit obligations and for backup purposes. Publisher and payout records are retained as required by tax and financial regulations in the relevant jurisdictions. To permanently delete your account and associated data, email support@stck.me from your registered email address; we’ll process the request after verification.

10. Children’s privacy

Stck does not knowingly collect personal information from children under 16, and the Service is not directed at children under 16. If we learn we’ve collected data from a child under the applicable minimum age without appropriate consent, we’ll delete it promptly. Contact community@stck.me if you believe we may have such information.

11. Links to other websites and services

We aren’t responsible for the practices of third-party sites linked from Stck, including our distribution and retail partners’ own storefronts. Their privacy policies govern your use of their services.

12. California and other U.S. state privacy rights

California users have rights under the California Consumer Privacy Act, as amended by the California Privacy Rights Act (CPRA). Stck does not sell personal information as defined under the CCPA/CPRA.

California (and, depending on where you live, residents of other states with comprehensive privacy laws such as Virginia, Colorado, Connecticut, or similar) may have the right to:

  • Request access to the personal information we hold about you;

  • Request deletion of your personal information;

  • Correct inaccurate information;

  • Opt out of the sale or sharing of personal information (Stck does not sell your information).

Contact community@stck.me to make a request; we’ll verify your identity via your account email and, if necessary, proof of residency.

13. Changes to this Policy

We may update this policy to reflect current practices or legal requirements. We’ll update the “Last Updated” date, and notify you by email or a prominent notice on the Service for material changes.
