Privacy Policy

When you use newsletter sign-ups or lead-magnet PDF downloads on the Website, we may collect:

• Email address
• Optional source tag indicating which page you subscribed from (for example, a calculator or guide slug)
• Any other information you voluntarily type into a signup field

When you submit your email address through any signup form on this site - including newsletter sign-ups and lead-magnet PDF downloads such as the 2026 Freelancer Tax Checklist - your email is sent via our Vercel-hosted subscribe endpoint to Buttondown, our email service provider (buttondown.com). Buttondown processes your email under their own privacy policy. We use your email to send the requested resource, occasional editorial updates, and freelance tax tips. You can unsubscribe at any time using the link in any email.

When you visit our Website, we and our processors may automatically collect certain technical data, including:

• IP address (which may be anonymised or truncated for analytics; may also be forwarded to Buttondown for spam/firewall checks when you subscribe)
• Browser type and version
• Operating system and device type
• Pages visited and time spent on each page
• Referring URLs (the page you came from)
• Date and time of your visit
• General geographic location (country/region level, derived from IP)
• Your privacy choices. If you are in the EEA, the UK or Switzerland, your consent choice is stored by Google's consent tool. Elsewhere, if you use "Do Not Sell or Share My Personal Information", we store that opt-out in your browser (local storage).

Values you enter into calculators and generators on the Website (for example income figures, rates, or invoice fields) are processed in your browser for the purpose of showing results on that page. We do not collect, store, or transmit those tool inputs to our servers as part of the calculation itself. If a page also offers an email signup or PDF lead magnet, only the email-related data described in Section 3.1 is sent to our processors.

We use cookies and local storage to operate and improve our Website. See Section 9 (Cookies Policy) for full details.

Provider: Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA

Role: Analytics processor - collects and processes usage data to help us understand how visitors interact with our Website.

Data Processed: IP address (anonymised), device and browser data, pages visited, session duration, events and interactions.

Privacy Policy: policies.google.com/privacy

Opt-Out: tools.google.com/dlpage/gaoptout, or use "Do Not Sell or Share My Personal Information" in our footer (outside the EEA, UK and Switzerland).

We have enabled IP anonymisation in GA4. Data may be transferred to the United States. Google acts as a data processor under a Data Processing Addendum that incorporates Standard Contractual Clauses (SCCs).

When it runs. If you are in the EEA, the UK or Switzerland, Google Analytics runs only if you consent in our consent tool. Everywhere else, it runs by default. We have turned off Google signals and ads personalisation for analytics hits from this site, so your analytics data is not used to personalise ads. Outside the EEA, the UK and Switzerland, you can switch analytics off with "Do Not Sell or Share My Personal Information" in the footer, and it is switched off automatically if your browser sends a Global Privacy Control signal.

How long. Google Analytics keeps user-level data for 2 months, after which only aggregated reports remain.

Provider: Google Ireland Limited (for visitors in the EEA and Switzerland) and Google LLC.

Role: Advertising technology provider - serves contextual and/or personalised advertisements on our Website.

Data Processed: Cookie and device identifiers, IP address (used for approximate location and ad delivery), browser and device information, the page you are viewing, ad interactions and, for personalised ads only, browsing activity across sites.

Privacy Policy: policies.google.com/privacy

Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this Website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to this Website and/or other sites on the Internet.

You may opt out of personalised advertising by visiting Google Ad Settings at myadcenter.google.com. You may also opt out of some third-party vendors' use of cookies for personalised advertising by visiting www.aboutads.info. These options are in addition to the choices in Section 7.2A and Section 9.3.

Other third-party vendors and ad networks may also serve ads on this Website through Google AdSense and may use cookies to do so. Where a vendor offers it, you may opt out of that vendor's use of cookies for personalised advertising at www.aboutads.info. For more information about how Google uses data from websites that use its services, see policies.google.com/technologies/partner-sites.

How ads work on this site. This site is free because it shows ads from Google AdSense. To deliver ads, Google (and, where you allow it, other ad partners listed in our consent tool) may store or read small files such as cookies, or similar identifiers, on your device. Google does this even for non-personalised ads. Non-personalised ads are not based on your past browsing, but they still use cookies to limit how often you see the same ad, to detect fraud and invalid clicks, and to measure ads in aggregate. Personalised ads also use information about your activity across sites to choose ads.

If you are in the EEA, the UK or Switzerland. Google's ad code loads when you arrive so that it can show our consent tool, which is provided through Google's certified consent platform. No advertising cookies are set, and no personalised ads are shown, until you make a choice. You can consent to all, refuse all, or choose by purpose and partner, and the "Consent" and "Do not consent" buttons appear together on the first screen. We rely on your consent both to store and read cookies or identifiers on your device and for the processing of personal data that follows (GDPR Art. 6(1)(a)). If you refuse consent, Google may still show a "limited" ad. Limited ads are not personalised. Google may use a cookie or local storage only to detect invalid traffic and fraud, and your IP address is used to deliver the ad.

If you are anywhere else, including the United States. See section 7.2A.

Google's role. For its own advertising purposes, such as measuring ads, fighting fraud and personalising ads, Google acts as an independent controller of your personal data under its own privacy policy. We decide to place Google's ad code on our site, and we are responsible for that choice and for the choices we offer you. We do not receive the data Google collects through its cookies. You can read how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites, and manage Google ad personalisation at myadcenter.google.com.

How long. If you are in the EEA, the UK or Switzerland, your choice is stored by Google's consent tool, and then we ask you again after the period set in that tool. Outside Europe, an opt-out is stored in your browser until you clear it. Google's advertising cookies last for the periods shown in our consent tool's partner list, and Google keeps the data under its own retention policy.

Transfers. Google may process data in the United States. Google LLC is certified under the EU-US Data Privacy Framework and also uses Standard Contractual Clauses.

Provider: Vercel Inc., 340 Pine Street, Suite 900, San Francisco, CA 94104, USA

Role: Hosting and infrastructure provider - hosts the Website and processes server-side request data.

Data Processed: IP addresses, HTTP request headers, server logs.

Privacy Policy: vercel.com/legal/privacy-policy

Vercel processes data as a data processor under a Data Processing Agreement. Data may be transferred to the United States under appropriate safeguards.

Provider: Buttondown LLC (Buttondown), USA

Role: Email newsletter and lead-magnet processor - stores subscriber email addresses, sends subscription confirmation emails, delivers the generic 2026 Freelancer Tax Checklist PDF link, and sends occasional newsletter emails when you opt in on our tool or guide pages.

Data Processed: Email address, optional source tag indicating which page you subscribed from (e.g. a calculator or guide), subscription status (including double opt-in confirmation), and subscriber IP address when provided by our subscribe endpoint for spam/firewall checks. We do not send calculator inputs or other personal financial data to Buttondown.

Privacy Policy: buttondown.com/legal/privacy

We use double opt-in: after you submit your email, Buttondown sends a confirmation link. Your address is not added to our mailing list until you confirm. The generic checklist PDF may download immediately in your browser after signup; the same PDF is also linked from our confirmation email. Legal basis: consent (Art. 6(1)(a) GDPR) for EEA/UK users; your consent for US users.

We share your email with Buttondown solely for the purpose of email delivery and list management. No other data is shared with third parties for marketing.

Our Website may contain links to external websites or embed content from third-party services. We are not responsible for the privacy practices of those third parties. We encourage you to review the privacy policies of any external sites you visit.

If you are located in the European Economic Area (EEA) or the United Kingdom, you have the following rights under the GDPR or UK GDPR:

• Right of Access (Art. 15): You may request a copy of the personal data we hold about you.
• Right to Rectification (Art. 16): You may request that we correct any inaccurate or incomplete personal data.
• Right to Erasure (Art. 17): You may request that we delete your personal data ("right to be forgotten"), subject to certain legal exceptions.
• Right to Restriction of Processing (Art. 18): You may request that we limit how we use your data while a dispute is resolved.
• Right to Data Portability (Art. 20): Where processing is based on consent or contract, you may request your data in a structured, machine-readable format.
• Right to Object (Art. 21): You may object to processing based on legitimate interests, including profiling. You may also withdraw consent at any time without affecting the lawfulness of processing before withdrawal. Where we rely on legitimate interests you can object at any time. Where the processing is for advertising, we will stop.
• Right to Lodge a Complaint: You have the right to lodge a complaint with your supervisory authority. In Ireland, this is the Data Protection Commission (DPC): dataprotection.ie. In the UK, this is the Information Commissioner's Office (ICO): ico.org.uk.

If you are a California resident, you have the following rights:

• Right to Know: You may request disclosure of the categories and specific pieces of personal information we have collected about you, the sources of that information, the purposes for collection, and the categories of third parties with whom we share it.
• Right to Delete: You may request the deletion of personal information we have collected from you, subject to certain exceptions.
• Right to Correct: You may request correction of inaccurate personal information we maintain about you.
• Right to Opt-Out of Sale or Sharing: We do not sell personal information for monetary consideration. To the extent that sharing personal data with advertising partners (such as Google AdSense) constitutes "sharing" under the CPRA, you may opt out by using "Do Not Sell or Share My Personal Information" in our footer or by turning on Global Privacy Control in your browser (see section 7.2A) or by managing ad personalisation at myadcenter.google.com.
• Right to Non-Discrimination: We will not discriminate against you for exercising any of your privacy rights.

Default ads. If you visit from outside the EEA, the UK and Switzerland, we show Google ads by default, and these may be personalised. We are based in Ireland, so EU data protection law (GDPR) applies to how we handle your data wherever you are.

Your choices.

• Opt out. Click "Do Not Sell or Share My Personal Information" in the footer of any page. If you are in a US state covered by Google's US privacy tool, the link opens Google's opt-out. Everywhere else, we save your choice in your browser. Either way, from then on you see only non-personalised ads and Google Analytics is switched off for your visits, and we ask Google to use "restricted data processing" for your visits, so Google does not use your data to build or use an advertising profile about you. Google may still use cookies or similar identifiers to deliver ads, limit repeats, prevent fraud and measure ads. Your choice applies to this browser and device, and clearing your cookies or site data removes it.
• Global Privacy Control. If your browser sends a Global Privacy Control (GPC) signal, we treat it as a request to opt out: you see only non-personalised ads and Google Analytics is switched off, without having to click anything.

US state privacy rights. Depending on your state (for example California, Colorado, Connecticut, Virginia and others), you may have the right to know about, access, correct and delete your personal information, and to opt out of its "sale", its "sharing" for cross-context behavioural advertising, or targeted advertising. We do not sell personal information for money. Personalised ads may count as "sharing" or "targeted advertising" under some state laws, and you can opt out as described above. We will not treat you differently for using these rights. To make a request, email freelancemath.mail@gmail.com. We respond within 45 days, and you can appeal a refusal by replying to our response.

To exercise any of the above rights, please contact us at:

Email: freelancemath.mail@gmail.com

Please include your name, email address, country of residence, and a description of your request. We will respond within 30 days (GDPR) or 45 days (CCPA) of receiving a verifiable request. We may need to verify your identity before processing your request.
