Legal & policies.

Information we collect.

We collect what we need to respond to inquiries, deliver services, and operate the site. Nothing more.

How we use it.

We use the information we collect for service delivery, site operation, and communications you've consented to. We do not sell your personal data.

• Inquiry response. Respond to messages and provide requested services.
• Site operations. Operate, maintain, debug, and improve the site and client experience.
• Engagement updates. Send transactional updates related to active engagements, deliverables, or account activity.
• Marketing communications. Send marketing messages only where you have provided affirmative opt-in consent.
• Legal compliance. Meet our obligations under applicable law — including consent records and audit trails.

Storage, retention & sharing.

Data is stored with reputable providers and shared only with vendors operating on our behalf. Records are kept only as long as we need them — or as long as the law requires.

Storage & retention

• Data is stored using reputable providers and protected with reasonable administrative, technical, and physical safeguards.
• We retain data only as long as necessary for the purposes described, or as required by applicable law.
• Consent records and opt-out documentation are retained for a minimum of four (4) years in compliance with TCPA statute of limitations requirements.

Sharing & third parties

• We do not sell your personal data.
• We may share data with trusted vendors (hosting, analytics, email and SMS delivery) strictly for operational purposes.
• Vendors are contractually required to protect data using industry-standard security practices.
• We do not share SMS opt-in data, text messaging originator information, or consent records with third parties — other than messaging service providers acting on our behalf.

Your rights.

You have specific rights over the data we hold about you. To exercise any of them, email info@stacklumen.com. We respond within 30 days and may need to verify your identity first.

• Access, correct, or delete your personal data, subject to legal exceptions.
• Withdraw consent for marketing communications at any time without penalty.
• Opt out of non-essential communications at any time via the mechanism in each message.
• Request details on how your data is processed and shared.
• Lodge a complaint with your local data-protection authority.

How we use cookies.

Cookies are small text files stored on your device when you visit a website. They help sites remember preferences, analyze usage, and improve the experience. Here's how we use them.

Why we use cookies

• Remember your preferences — dark mode, language settings, return-visit state.
• Analyze site performance — which pages are visited, how long sessions last, where things break.
• Improve functionality — smooth navigation, personalized content, fewer interruptions.
• Understand marketing effectiveness — which campaigns drive traffic and conversion.

Cookies we set

• stacklumen-cookie-consent — stores your cookie preferences (365 days).
• stacklumen-cookie-consent-timestamp — tracks when preferences were set (365 days).
• stacklumen-dark-mode — remembers your theme preference (365 days).
• stacklumenLoaderLastRun — prevents loader animation on every page load (session).

Categories & third parties.

Four categories cover everything we use. Some are essential and can't be turned off; the rest are opt-in.

Third-party cookies

We use third-party services that set their own cookies, including Google Analytics, Google Tag Manager, Facebook Pixel, Hotjar, and Webflow. These services have their own privacy policies — we recommend reviewing them independently.

Your choices.

You're in control. Accept all, customize by category, or decline non-essentials — and update your choice anytime.

First visit

When you first visit the site, a consent popup lets you (a) accept all cookies, (b) customize preferences by category, or (c) decline non-essential cookies.

Updating later

You can update your preferences at any time via Cookie Settings in the "Made in Webflow" badge menu at the bottom-left of any page.

Updates to this policy

We may update this Cookie Policy periodically. The "Effective" date at the top of this page reflects the latest revision. Continued use of the site constitutes acceptance of the revised policy.

SMS — consent & opt-out.

Stacklumen LLC · stacklumen.com. SMS and MMS messages governed by FCC and TCPA rules. Opt-in is always affirmative; opt-out is always honored.

Opt-in consent

You will only receive SMS or MMS messages from Stacklumen LLC after providing prior express written consent via a clear, documented opt-in mechanism — a website form, written agreement, or explicit digital sign-up. Consent must be freely given, specific, and informed.

Providing consent to receive text messages is never a condition of purchasing goods or services. Pre-checked consent boxes are not used and will not be accepted as valid consent. When you opt in, you'll receive a disclosure message confirming the types of messages, frequency, that message and data rates may apply, and how to opt out.

Opt-out instructions

You may revoke SMS consent at any time through any reasonable method:

• Reply STOP, QUIT, END, CANCEL, UNSUBSCRIBE, or REVOKE to any message.
• Email info@stacklumen.com.
• Submit a request through our website contact form.
• Any other reasonable means clearly communicating your intent to stop receiving messages.

Message & data rates

Message and data rates may apply depending on your carrier and plan. Stacklumen LLC is not responsible for charges incurred. Carriers are not liable for delayed or undelivered messages.

Email — operational & marketing.

Two distinct email categories. Operational messages support active relationships and don't require marketing consent. Marketing messages require affirmative opt-in.

Operational communications

If you contact us or enter into a service relationship, we may email you regarding operational topics — proposals, invoices, onboarding, project updates, deliverables, access credentials, and service announcements. These operational emails are necessary to perform or manage a service relationship and do not require separate marketing consent.

• We may use third-party email providers to send and store operational communications.
• Attachments and links may be used for deliverables, approvals, and documentation.

Marketing communications

Marketing emails — newsletters, announcements, case studies, promotional content — are sent only to recipients who have provided affirmative opt-in consent, or where another lawful basis applies under applicable law. We do not send unsolicited marketing emails.

• Consent. We obtain explicit, documented opt-in before adding recipients to marketing lists. Consent is never assumed from a business relationship alone.
• Unsubscribe. Every marketing email includes a clear, functional unsubscribe link. Opt-out requests are honored within 10 business days per CAN-SPAM. Mechanisms remain functional for at least 30 days after sending.
• No pre-checked boxes. Consent must be an active, affirmative action.
• Physical address. All commercial emails include a valid physical postal address per CAN-SPAM.
• No selling data. We do not sell or transfer email addresses to third parties, except service providers engaged for delivery or compliance.

Consent records

We maintain records of all consent — date, time, method (web form, SMS keyword, written agreement), and the exact language presented at the point of opt-in. Records are retained for a minimum of four (4) years per TCPA statute of limitations.

Conduct & data use.

Stacklumen is a remote-first team. Our focus is deep work, clear writing, and predictable communication — not reactive, high-frequency messaging.

Communication standards

• Respectful conduct. All team members must be treated with professionalism. Harassment, intimidation, discriminatory language, or hostile conduct are not tolerated.
• Response windows. Unless otherwise specified in a contract or SLA, messages are handled within reasonable business timelines.
• Consolidated communication. We ask clients to provide consolidated feedback, timely approvals, and complete information to enable efficient execution.
• After-hours contact. Non-urgent after-hours or weekend messages may not receive same-day responses.

Data use — SMS & email

Stacklumen LLC does not share SMS consent data, opt-in records, or text messaging originator information with third parties, affiliates, or non-affiliates — except as strictly necessary with messaging service providers acting on our behalf. All such providers are bound by data-protection obligations. This restriction explicitly excludes SMS opt-in data from any other data sharing described elsewhere.

For email, service providers may be used for delivery and performance measurement. All opt-out requests are honored within required timeframes under applicable law.

Policy updates

Stacklumen LLC may update this Communications Policy to reflect legal requirements or operational changes. Updates are posted on this page with a revised effective date.

Master Services Agreement.

The MSA governs paid service engagements with Stacklumen LLC — project terms, payment, IP, deliverable handover, and the obligations on both sides.

Upgrade terms.

These terms govern paid and complimentary upgrades to the Stacklumen Framework — our native Webflow and Astro standard — including migrations from older Webflow code-embed builds and dated Wix sites.

• No guarantee of results. An upgrade improves the technical foundation of your site. We do not guarantee any specific business outcome — traffic, rankings, conversions, revenue, or leads — and no such result is promised or implied.
• Subjective preference is not a defect. Design and styling involve taste. A difference in subjective visual preference does not constitute a defect, error, or breach, and is not grounds for a refund or rework obligation.
• Indemnification & hold harmless. To the maximum extent permitted by law, you agree to indemnify and hold Stacklumen LLC fully harmless from any claim, loss, or liability arising from an upgrade — except in cases of gross negligence or willful misconduct on our part.
• Free upgrades are discretionary. Stacklumen may, at its sole discretion, provide an upgrade at no charge. A complimentary upgrade confers no additional warranty, creates no ongoing obligation, and may be offered or withdrawn at our discretion.
• Provided as-is. Upgrades and migrations are delivered on an as-is basis under the applicable engagement terms. All other terms of the Master Services Agreement continue to apply.
