Privacy Statement

Privacy isn’t a checkbox for us. We collect what we need to ship you a unit, keep you posted on safety, and improve the next one — and not much else. This page explains what we collect, why, and what you can do about it.

Effective May 3, 2026.

This applies whenever you visit our website at dartsolar.com, place an order, sign up for the waitlist, email us, or otherwise interact with us online. A quick note on terms: when we say “we” or “us,” we mean DartSolar LLC, a California limited liability company. When we say “the site,” we mean dartsolar.com and any of its pages, forms, and storefronts. When we say “you,” we mean the human reading this.

At a glance

  • WE DON’T SELL, RENT, OR TRADE YOUR PERSONAL INFORMATION. PERIOD.

  • WE DON’T USE YOUR DATA TO TRAIN THIRD-PARTY AI MODELS, AND WE DON’T LET OUR ANALYTICS VENDORS DO IT ON OUR BEHALF.

  • WE COLLECT WHAT’S NEEDED TO SHIP, SUPPORT, AND KEEP YOU SAFE — NOTHING MORE.

  • YOU CAN ASK TO SEE, CORRECT, OR DELETE WHAT WE HAVE ABOUT YOU. EMAIL LEGAL@DARTSOLAR.COM.

The other agreements at play

This document covers what we do with your information. Three sister documents cover the rest of the relationship:

What we collect

We collect three kinds of information.

Information you give us. Your name, email address, phone number, shipping and billing address, payment details, vehicle make and model (so we can confirm compatibility), order notes, support messages, and anything else you put in a form or email. You decide what to share — we ask only for what we need to fulfill the order or answer the question.

Information we get automatically. When you visit the site, our servers and the analytics tools we use receive your IP address, browser type and version, operating system, the pages you view, the time of your visit, and the page that referred you. This is the same information any web server logs by default.

Information from cookies and similar technologies. Cookies, web beacons, and pixels help the site remember you between pages and tell us which parts of the site are working. Most browsers let you decline cookies entirely or selectively — the site will still work, though some pages may behave a little differently.

Why we collect it

Each piece of data has a job. Here’s what we use yours for:

  • To fulfill your order — ship the unit, process payment, hand off to the carrier, manage returns.

  • To support you — reply to your messages, troubleshoot issues, and resolve warranty claims.

  • To keep you safe — reach you with safety notices, recall information, or update bulletins under our Limited Warranty and Product Liability Agreement. Because every order is registered automatically when it ships, we use your contact details to reach you about the specific unit you bought.

  • To improve the site, the product, and the documentation — what worked, what confused people, what to fix next.

  • To meet our legal obligations — tax, accounting, fraud prevention, and any government request that we’re actually required to comply with.

Who we share it with (and don’t)

We don’t sell, rent, or trade your personal information to outside parties. We never have. We don’t plan to. If that ever changes, we’ll tell you in a way you can’t miss, and we’ll give you a chance to opt out before any sharing starts.

We do share your information with a small set of vendors that help us run the business, and only the slice they need to do their job:

  • Payment processors, to take your money and refund it when needed.

  • Carriers (UPS, FedEx, freight lines), to get the unit to your door.

  • Email and SMS providers, to send you order updates and safety notices.

  • Web analytics providers (Squarespace Analytics, Google Analytics, Clicky, Matomo), to understand traffic patterns on the site.

  • Cloud hosting and engineering tools, to keep the site online and the order book intact.

We also disclose information when we’re legally required to — in response to a valid subpoena, court order, or other lawful request — or when it’s necessary to protect the rights, safety, or property of DartSolar, our customers, or the public.

If we’re ever part of a merger, acquisition, financing, or sale of assets, customer information may move with the business. The buyer would be bound by the commitments in this Privacy Statement to anything they receive from us, and you’d hear from us before anything changes.

Email and SMS communications

We send two flavors of message.

Transactional messages. Order confirmations, shipping updates, warranty correspondence, and safety notices about the unit you bought. These aren’t marketing — they’re part of the relationship, and you can’t fully opt out without ending the relationship. If you’ve given us a phone number, safety notices may also come by SMS as described in our Limited Warranty. Standard message and data rates from your carrier may apply.

Marketing messages. Newsletters, product announcements, and the occasional update on what we’re building. These only go to people who’ve asked to hear from us, and every one of them has an unsubscribe link at the bottom. To stop SMS marketing, reply STOP to any message we send. Opting out of marketing doesn’t end transactional or safety communications — we still need a way to reach you about your order and your unit.

Cookies and analytics

We use cookies and similar technologies to keep the site working and to understand how it’s used. Browser-level activity on the site may be aggregated by Squarespace Analytics, Google Analytics, Clicky, and Matomo. Each of those tools handles data on its own terms — please review their respective Terms & Conditions and Privacy Policies to learn how they collect and process information when you visit any site that uses them.

Most browsers let you control cookies through their settings — including blocking them outright, deleting them, or being warned before one is set. Some parts of the site (the storefront in particular) won’t work as well without cookies, but you’re welcome to try.

If your browser sends a Global Privacy Control (GPC) signal, we treat it as an opt-out of any "sale" or "sharing" of your personal information for behavioral advertising under the meaning of California law. We don’t engage in either today, but the signal is honored as a matter of course.

AI and machine-learning training

We don’t use your personal information, your support tickets, your photos, or your installation videos to train third-party generative AI or machine-learning models. We don’t sell or license your data to anyone who does. If we ever build internal tools that learn from aggregated, de-identified product data — for example, identifying common installation pain points across a region — we’ll do it without anything that points back to you, and we’ll spell it out here before we start.

How long we keep things

We hold onto your information only as long as we have a reason to. In practice that means:

  • Order and payment records: as long as required by tax and accounting law (typically seven years in the United States).

  • Warranty registrations and serial-number records: for the warranty period plus the post-warranty parts-availability window described in the Limited Warranty — so we can reach you if a safety issue surfaces.

  • Support correspondence: typically three years from the last interaction.

  • Marketing list entries: until you unsubscribe or ask us to delete you.

  • Web analytics: rolling windows set by each provider, generally up to 26 months of aggregated data.

When the reason to keep something runs out, we delete it or strip it to anonymized aggregate data.

How we protect it

We use technical and organizational safeguards proportionate to the sensitivity of the data — encrypted connections (HTTPS), encrypted storage where supported by the vendor, access limited to staff who need it, and vendor agreements that contractually require comparable protection on their end. No system is perfect, and we don’t promise an impenetrable one. If we ever discover a breach that affects you, we’ll tell you as quickly as the law allows and walk you through any steps that make sense.

California customers

If you’re a California resident, the California Consumer Privacy Act (as amended by the California Privacy Rights Act) gives you specific rights. You can ask us to:

  • Know. Tell you what categories of personal information we’ve collected about you in the last 12 months, where we got it, why we have it, and who we’ve shared it with.

  • Access. Send you a copy of the specific personal information we hold.

  • Correct. Fix inaccurate personal information.

  • Delete. Erase your personal information, subject to the legal exceptions California law allows (for example, we have to keep tax records).

  • Limit use of sensitive information. Restrict how we use any "sensitive personal information" within the meaning of California law (we currently don’t collect any in that statutory sense, but the right exists).

  • Opt out of sale or sharing. We don’t sell or share your personal information for cross-context behavioral advertising, but you can confirm that election. A Global Privacy Control signal from your browser will be honored as an opt-out without you needing to do anything else.

  • Be free from retaliation. We won’t deny you service, charge you a different price, or give you a worse product because you exercised any of these rights.

To make a request, email legal@dartsolar.com from the email address on your order, or write to us at the address at the bottom of this page. We may need to verify your identity before we hand over personal information — usually by confirming a few details from your order. We’ll respond within 45 days, with one 45-day extension if the request is complex (and we’ll tell you if we need it). You can also designate an authorized agent to act for you with written authorization.

European customers

DartSolar ships throughout the globe. If you’re in the European Economic Area, the United Kingdom, or Switzerland, the GDPR (or UK GDPR or the Swiss data-protection law) applies to your information. The lawful bases we rely on are:

  • Performance of a contract — to fulfill orders you place and provide warranty service.

  • Legitimate interests — to keep the site secure, improve the product, prevent fraud, and run our business in a normal way. You can object to any of this at any time.

  • Consent — for marketing emails and any non-essential cookies that require it. You can withdraw consent at any time by unsubscribing or adjusting your browser settings.

  • Legal obligation — for tax, accounting, and product-safety records.

You have the right to access, correct, delete, restrict, or object to processing of your personal data, the right to data portability, and the right not to be subject to a decision based solely on automated processing. To exercise any of these rights, email legal@dartsolar.com. You can also lodge a complaint with the data-protection authority of your country if you think we’ve mishandled your information — though we’d ask you to talk to us first.

International transfers. Our servers and most of our vendors are in the United States. When we transfer personal data out of the EEA, the UK, or Switzerland, we rely on the European Commission’s Standard Contractual Clauses (or the UK’s International Data Transfer Addendum, or the Swiss-equivalent mechanism) with our service providers, plus any supplementary safeguards required by case law. Copies are available on request to legal@dartsolar.com.

Children’s privacy

The site isn’t designed for children, and we don’t knowingly collect personal information from anyone under 13 (or under the equivalent local age in your country). If you’re a parent or guardian and you believe your child has given us information without your permission, email legal@dartsolar.com and we’ll delete it. People between the local age of digital consent and 18 should review this Privacy Statement with a parent or guardian before submitting personal information.

Changes to this statement

We may update this Privacy Statement from time to time. When we do, we’ll change the effective date at the top of this page and, for material changes, we’ll do our best to flag them — for example, by posting a notice on the site or emailing customers we have a relationship with. Continuing to use the site after a change is your acceptance of the new statement. Updates won’t retroactively reduce the protections you had when you originally gave us your information.

The legal bits

Some of this part has to read a certain “legal” way to do its job, but the gist is straightforward.

Other rights preserved. Several states and countries impose mandatory privacy protections that may differ from this Privacy Statement. Where the law of your state or country of residence requires terms more protective of you than what’s described above, those terms apply to your use of the site to the extent required by that law. This statement is not intended, and should not be read, to override any non-waivable privacy right you have under state, federal, or international law.

Governing law. This Privacy Statement is governed by the laws of the State of California, without regard to conflict-of-laws rules — except where the privacy law of your state or country requires otherwise.

Severability. If any part of this Privacy Statement is held unenforceable, the rest still applies, and the unenforceable part is enforced to the maximum extent the law allows.
