This Privacy Policy explains what information Jumpstart Blockchain ("we", "us") collects when you visit jumpstartblockchain.com (the "Site"), how we use it, who we share it with, and the choices you have. By using the Site you agree to the practices described here. If you don't agree, please don't use the Site.
Who we are
Jumpstart Blockchain is an independent publication about blockchain development, with articles and a blockchain directory. For any privacy question or request, write to us through our contact page.
Information we collect
Information you give us
- Account (Google sign-in). When you sign in with Google, we receive your name, email address, profile photo and Google account ID. We use them to create your account. We never see your Google password.
- Profile. The username, name, bio and photo you choose. If you publish articles, your name, username, photo and bio appear publicly on your articles and on your profile page.
- Articles. Anything you write or publish through the Site, including drafts.
- Newsletter. Your email address and the time you confirmed it. Sign-up is double opt-in: we email you a short code, and you're only subscribed once you enter it.
- Contact form. Your name, email address, subject and message.
Information collected automatically
- Server logs. Like any website, our hosting receives technical data with each request, including your IP address, browser (user agent), the page requested, and the time. These logs are used to run and secure the Site and are kept for a limited time.
- Usage counts. We count article views and ad impressions and clicks. These counts are aggregate numbers per article or ad, per 15 minutes or day and device type. They are not tied to you. An IP address may be used briefly in memory to limit abuse, but it isn't stored with the counts.
- Cookies and similar technologies. Used by us and by our advertising and analytics partners. See Advertising, Analytics and our Cookie Policy.
Advertising
The Site is free because it shows ads. We work with the following advertising partners:
- Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this Site and/or other sites on the Internet.
- Ezoic. Ezoic and its partners serve and optimise ads on the Site and may use cookies and similar technologies to do so. See Ezoic's privacy policy. The partners Ezoic works with are listed at the end of this policy.
- Direct advertisers. We sometimes sell ad space directly to companies. Those ads are served from our own servers without third-party cookies. A click goes through a short redirect on our Site so we can count it, and then on to the advertiser.
Your choices about personalised ads:
- Opt out of personalised advertising from Google in Google's Ads Settings.
- Opt out of personalised ads from many third-party vendors at www.aboutads.info/choices (US) or www.youronlinechoices.eu (EU).
- Learn how Google uses information from sites that use its services.
If you opt out, you'll still see ads, but they won't be based on your browsing.
Analytics
We use Google Tag Manager to load analytics tools such as Google Analytics. They help us understand how the Site is used, for example which articles are read and how visitors find us. Ezoic also collects analytics about how pages and ads perform. These tools use cookies and collect information such as pages visited, time on page, device type and approximate location, derived from your IP address. You can opt out of Google Analytics with the Google Analytics opt-out browser add-on.
Consent (EEA, UK and Switzerland)
If you visit from the European Economic Area, the United Kingdom or Switzerland, a consent tool asks for your choices before non-essential cookies are used for advertising, personalisation or analytics. You can change or withdraw your consent at any time through that tool. If it doesn't appear, clear your cookies for jumpstartblockchain.com and reload the page.
How we use information
We use the information above to:
- provide the Site, your account and the features you ask for;
- publish the articles you submit, under your name;
- send the newsletter you subscribed to, and reply to your messages;
- show ads, and measure how the Site and its ads perform;
- keep the Site secure, and prevent spam, fraud and abuse;
- comply with legal obligations.
If you are in the EEA or UK, our legal bases are:
- performance of a contract, to provide your account and the features you use;
- consent, for the newsletter and for non-essential cookies (you can withdraw it at any time);
- legitimate interests, to run, secure and improve the Site;
- legal obligation, where the law requires it.
How we share information
We do not sell your personal information. We share it only with:
- Service providers that run parts of the Site for us, under contracts that limit how they can use it:
- our hosting and database providers;
- Twilio SendGrid, which sends email (newsletter confirmations);
- Cloudflare R2, which stores uploaded photos and images;
- Google, for sign-in.
- Advertising and analytics partners, as described above. They collect information directly through their cookies under their own privacy policies.
- The public, for what you choose to publish: your articles and public profile.
- Authorities, when the law requires it, or to protect the rights, property or safety of Jumpstart Blockchain, our users or others.
- A successor, if Jumpstart Blockchain is ever sold or merged. This policy would continue to apply to your information.
How long we keep it
| Information | Kept for |
|---|---|
| Account and profile | Until you ask us to delete your account |
| Published articles | Until you or we delete them |

Your rights
Depending on where you live (for example under the GDPR, the UK GDPR, or California's CCPA/CPRA), you may have the right to:
- access the personal information we hold about you;
- correct it (most of your profile can be edited on your profile page);
- delete it, including your account;
- object to or restrict certain processing;
- receive a copy of it in a portable format;
- withdraw consent at any time;

To make a request, contact us from the email address on your account, and tell us what you'd like us to do. We'll reply within 30 days. We won't treat you differently for exercising your rights.
Security
The Site is served over HTTPS. Your session cookie is signed and can't be read by scripts on the page. Access to our systems is restricted. No method of transmission or storage is completely secure, so we can't guarantee absolute security.
International transfers
We and our providers may process information in countries other than yours, including the United States. Where the law requires it, we rely on appropriate safeguards, such as the European Commission's Standard Contractual Clauses.
Children
The Site is not directed at children under 13 (or under 16 in the EEA and UK), and we don't knowingly collect their personal information. If you believe a child has given us personal information, contact us and we'll delete it.
Links to other websites
Articles and ads link to other websites. We're not responsible for their content or privacy practices. Check their policies before giving them any information.
Changes to this policy
We may update this policy from time to time. The date at the top shows when it last changed. If the changes are significant, we'll highlight them on the Site.
