Privacy at 1Dollars
How we handle data, calculator inputs, cookies and advertising
This Privacy Policy explains what information 1Dollars.org may collect when you browse the website, use a calculator, interact with advertisements or contact us; why that information may be used; which service providers may receive it; and the choices and rights that may be available to you.
1Dollars is an independent, general-audience calculator and educational platform. Most public calculators can be used without opening an account, providing a name or submitting payment details.
Privacy policy at a glance
These points provide a plain-language overview. The complete sections below explain the details and control if a summary and a detailed provision appear different.
Important calculator privacy point: Many 1Dollars tools perform their calculations through JavaScript in your browser. We do not intentionally use the values you type to create a personal account or make a decision about your eligibility for a loan, job, insurance policy, benefit, diagnosis or other service. The page may still load hosting, analytics, security, advertising or embedded technologies that process technical and interaction information.
1. Scope of this policy and who is responsible
This policy applies to 1Dollars.org, including its calculator pages, category directories, articles, contact features and other pages that link to this policy. It covers tools and content relating to money, tax, loans, investing, health, fitness, nutrition, math, science, education, dates, conversions, property, construction, travel, business, technology, metals, food, energy and other everyday topics.
For information controlled directly by the website, 1Dollars.org is the responsible website operator. References to “1Dollars,” “we,” “our” and “us” mean 1Dollars.org. “You” and “user” mean a visitor or person using the website.
This policy does not control the separate practices of Google, Microsoft, advertisers, affiliate merchants, social networks, linked websites or other third parties. Those providers may act as our service providers, independent controllers or businesses under their own terms and applicable law.
Current service model: At the date shown above, most public calculators do not require a 1Dollars account and 1Dollars does not ask for payment-card or bank-login information to use them. If a future feature has different data practices, an additional notice may be presented when the information is collected.
2. Information we may collect
The information available to us depends on what you do, the page you visit, your region, your consent choices, browser settings and the services currently active on that page.
Messages, feedback and requests
When you email us or use a contact feature, we may receive your name, email address, company, website, message, page URL, screenshots, attachments and any other details you choose to include.
We may also receive information when you report a calculator issue, request a correction, suggest a tool, make a privacy request or discuss advertising, media or a partnership.
Comments when Blogger comments are enabled
A comment may include your display name or profile, comment text, linked website, timestamp and information processed by Google or Blogger. Published comments can be visible to the public and may be indexed, quoted or copied by others.
Do not place personal, financial, health, account or confidential information in a public comment.
Device, network and usage data
Hosting, analytics, security and advertising technologies may process an IP address, approximate location, browser, operating system, device type, screen size, language, referrer, pages viewed, date and time, session duration, clicks, scrolling, errors and performance information.
Cookies, client IDs and advertising data
Cookies or similar technologies may assign browser, analytics, consent or advertising identifiers. Ad views, clicks, campaign parameters, referral source and affiliate attribution may also be processed to measure traffic, advertising or qualifying actions.
We do not ask you to provide a password, one-time password, complete payment-card number, bank-login credential or government identification number through a calculator. Please do not send that information through ordinary email, comments or general website forms.
3. Calculator inputs, results and local browser features
Calculator inputs can include amounts, rates, income, expenses, dates, ages, measurements, grades, quantities, body metrics, tax values, project dimensions or other figures needed to produce an estimate. You should enter only the minimum information required for the calculation.
Many tools are designed to calculate directly on the current browser page. In those cases, the values are used to produce the requested result and are normally cleared when you reset the tool, close the page or reload it, unless the tool provides a local history, preference, copy, print or download feature.
Some pages may store a preference or temporary tool state in cookies or browser local storage. Such information remains on your device until it expires, the tool removes it or you clear your browser data. A copied, printed or downloaded result is controlled by you after it leaves the page.
Never enter sensitive information into a calculator: passwords, one-time passwords, complete card or bank details, account login credentials, government ID numbers, tax-account identifiers, insurance policy numbers, complete medical records, precise home addresses, private keys or information about another person who has not agreed to its use.
Health, tax, insurance and financial calculators may ask for non-identifying numerical inputs. Use approximate or non-identifying values whenever an exact personal value is not necessary.
Calculator outputs are automated estimates requested by the user. They are not used by 1Dollars to approve, reject or determine eligibility for credit, employment, insurance, government benefits, medical treatment, education admission or any other decision with legal or similarly significant effects.
4. Cookies, local storage, pixels and similar technologies
1Dollars and its providers may use cookies, tags, pixels, scripts, local storage and related technologies. The exact technologies can change as the website, providers and consent settings change.
Essential operation
These technologies can support page delivery, load balancing, fraud prevention, spam protection, security, navigation and other functions requested by the user.
Remembering your choices
Consent systems may remember whether you accepted, rejected or customized non-essential technologies. Individual tools may also retain a stated browser preference or temporary setting.
Traffic and performance measurement
Analytics technologies can distinguish browsers or sessions and measure visits, traffic sources, interactions, device characteristics, errors and page performance.
Ad delivery and measurement
Advertising technologies can deliver contextual or personalized ads, limit repetition, measure performance, attribute conversions and detect invalid traffic.
Qualifying actions
An affiliate network or merchant may use a cookie or URL parameter to identify that a user reached its service through a 1Dollars link.
Third-party media or widgets
Embedded videos, social features, forms or other third-party components may collect information when they load or when you interact with them.
Blocking cookies may affect consent records, comments, embedded content, advertising, analytics or individual website features. Necessary platform technologies may still operate where permitted because the website cannot function correctly without them.
5. Platform, analytics and advertising providers
A service may load only on certain pages or only after a required consent choice. Provider features, cookie names and retention settings can change, so their own notices provide the most current description of their practices.
Hosting and site functions
1Dollars is published through Blogger, a Google service. Google may process technical information and cookies needed to deliver Blogger pages and features. If comments, contact forms, spam protection or other Google components are enabled, Google may process information connected with those interactions.
Review the Google Privacy PolicyAudience and usage measurement
Google Analytics may collect event-based information such as page views, traffic sources, device details, approximate location and interactions. Google Analytics can use identifiers such as a client ID to distinguish browsers and sessions.
How Google uses data from partner sitesAdvertising and measurement
Third-party vendors, including Google, may use cookies to serve ads based on a user's prior visits to 1Dollars or other websites. Google's advertising cookies can enable Google and its partners to deliver, limit, personalize and measure ads, subject to applicable consent and settings.

Microsoft Clarity may help us understand page use through interaction information such as clicks, scrolling, navigation, page rendering, heatmaps and session recordings. Clarity may use cookies and Microsoft may process information under its own privacy terms.
Review the Microsoft Privacy StatementEmail and contact handling
Email, contact-form and spam-filtering providers may process the sender, recipient, subject, message, attachments, technical headers and security information needed to deliver and protect communications.
Review the 1Dollars contact processLinks, merchants and social platforms
When you leave 1Dollars or interact with an external service, that provider may collect information under its own policy. This includes advertisers, affiliate merchants, government sites, financial institutions, social networks and embedded-media providers.
Read the third-party disclaimerClarity and sensitive fields: Providers may offer masking or exclusion settings, but no masking system should be treated as a reason to type confidential or sensitive information into a calculator, form or public comment.
6. Advertising, personalized ads and affiliate links
1Dollars may display advertisements supplied by Google AdSense or other advertising vendors. These providers may use cookies, device or browser identifiers and interaction information to deliver ads, limit how often they appear, measure results, prevent fraud and provide personalized advertising where permitted.
Google and its partners may select ads using information about visits to 1Dollars and other websites. Depending on your region and choices, the site may request consent before using personal data or non-essential storage for personalized advertising. Where consent is not available or not given, contextual or non-personalized advertising may be shown when supported.
You can manage Google advertising preferences through Google Ads Settings. You may also use participating-industry opt-out tools such as YourAdChoices. Opting out of personalized advertising does not necessarily remove advertisements; it generally changes how ads are selected.
Some pages may contain affiliate links. If you click one and complete a qualifying action, 1Dollars may receive a commission without increasing the price charged to you. The merchant or affiliate network may process referral identifiers and transaction-attribution information under its own privacy policy.
Sale or sharing terminology: We do not sell personal information directly for cash. However, some laws define the use of advertising or analytics identifiers as a “sale,” “sharing” or targeted advertising even when no money is exchanged for the information. Eligible users may use consent controls, a legally recognized browser signal where supported, or a privacy request to opt out of covered activities.
7. How we use information and legal bases
Why information may be processed
- Operate, maintain, secure and troubleshoot the website
- Deliver calculator pages and user-requested functions
- Understand traffic, interactions, errors and performance
- Improve formulas, accessibility, navigation and content
- Respond to messages, corrections and privacy requests
- Measure advertising, referrals and affiliate performance
- Detect spam, abuse, fraud and invalid activity
- Comply with legal obligations and protect legal rights
Why processing may be lawful
- Your consent, including consent for non-essential cookies or personalized ads
- Our legitimate interests in operating, securing and improving a free website
- Taking steps you request, such as responding to a message or privacy request
- Compliance with a legal, regulatory or court obligation
- Establishing, exercising or defending legal claims
Where processing relies on consent, you may withdraw that consent for future processing through available controls. Withdrawal does not make earlier processing unlawful.
8. How information may be disclosed
We may disclose limited information to the categories of recipients below when reasonably necessary for the purposes described in this policy:
- Hosting, content-delivery, analytics, advertising, consent-management and security providers
- Email, contact-form, spam-prevention and communication providers
- Affiliate networks, merchants and advertising partners for referral or campaign attribution
- Professional advisers, auditors or contractors subject to appropriate duties
- Courts, regulators, law enforcement or government authorities when legally required
- A buyer, successor or adviser involved in a reorganization, merger, financing or transfer of the website
- Other parties when you direct us to share information or give valid consent
Information in a public comment or other intentionally public submission may be visible to anyone. We may also disclose information when necessary to investigate abuse, prevent harm, protect users, enforce rights or secure the website.
Service providers may process information on our behalf or for their own stated purposes. Their role depends on the service, contract and applicable law.
9. Retention and deletion
We retain information only for as long as reasonably necessary for the purpose for which it was collected, to maintain security and records, resolve disputes, comply with law and protect legitimate interests. Retention can differ by data type and provider.
Email, requests and attachments
Communications may be retained while we respond, document a correction or request, prevent repeat abuse, maintain business records or meet legal obligations. Unnecessary attachments may be deleted earlier.
Blogger-hosted contributions
Comments may remain visible until removed by the author, 1Dollars or the platform. Copies can remain in backups, search indexes or third-party archives outside our direct control.
Provider-controlled records
Analytics, advertising, consent and hosting providers retain information according to their current settings, contracts and privacy policies. Aggregated or de-identified information may be kept longer where lawful.
Local storage and downloads
Information stored locally on your device remains until it expires or is cleared by you, the browser or the page. Printed, copied or downloaded calculator results are retained wherever you save or share them.
Because most calculators do not create an account, we may not be able to locate or associate anonymous technical information with a specific person.
10. Security
We use reasonable administrative, technical and organizational measures designed to protect information against unauthorized access, alteration, disclosure, loss and misuse. We also rely on security controls provided by our hosting, analytics, advertising and communication providers.
No website, email system, browser storage method or internet transmission can be guaranteed completely secure. Do not use ordinary email, comments or calculator fields to send information that could cause harm if exposed.
If we become aware of a breach affecting information for which we are responsible, we will investigate and provide notices when required by applicable law.
11. Your privacy rights
Depending on where you live and the law that applies, you may have some or all of the following rights:
Access and transparency
Request information about personal data associated with you, the purposes for using it, categories of recipients and available retention information.
Correction and deletion
Ask us to correct inaccurate information or delete eligible information, subject to legal exceptions and our ability to identify the relevant record.
Restriction, objection and portability
Request restriction, object to certain processing or receive eligible information in a portable format where these rights apply.
Consent and advertising choices
Withdraw consent, object to direct marketing, or opt out of covered sale, sharing or targeted advertising activities where applicable.
Appeal and complaint
Appeal a privacy-request decision where required and complain to an appropriate privacy or data-protection authority.
Equal treatment
Exercise applicable privacy rights without unlawful discrimination or retaliation.
How to submit a request: Email contact@1dollars.org with the subject line Privacy Request. Describe the request, your country or state when relevant, and the email address or communication involved. Do not send identity documents unless we specifically request a safe verification method.
- Request received We review the request, applicable location and information involved.
- Verification We may ask for proportionate information to confirm identity or authority.
- Search and review We assess records we control and any legal exception or limitation.
- Response or appeal We respond within the period required by applicable law and explain an available appeal method when required.
An authorized agent may submit a request where local law permits. We may require proof of authorization and may still contact the individual to verify the request. Requests may be limited when we cannot verify identity, cannot connect anonymous information to you, must keep a record by law or have another lawful basis to decline.
12. Cookie, analytics and advertising choices
- Website consent controls: Use the privacy or cookie message displayed on the site, where available, to accept, reject or customize non-essential purposes.
- Browser controls: Block or delete cookies and local storage through your browser settings. This may affect comments, preferences, embedded features and consent records.
- Google advertising: Manage personalization through Google Ads Settings.
- Google Analytics: Google provides an optional Analytics Opt-out Browser Add-on for supported browsers.
- Industry opt-outs: Use YourAdChoices for participating advertising companies. Its availability and effect vary by browser, device and region.
- Browser privacy signals: Where legally required and technically supported, a recognized opt-out preference such as Global Privacy Control may be processed by our consent or advertising systems.
“Do Not Track” is not interpreted consistently across websites and providers, so 1Dollars does not treat it as a universal opt-out signal. This does not limit rights available under applicable law or a supported Global Privacy Control signal.
13. International processing
1Dollars is available worldwide, and our service providers may process information in countries other than the country where you live. Those countries may have different privacy laws. Where required, the relevant provider or website operator may rely on consent, contractual safeguards, adequacy decisions or another lawful transfer mechanism.
By using third-party features, you may also interact directly with providers operating in other jurisdictions. Review their policies before submitting information.
14. Children's privacy
1Dollars is a general-audience calculator and educational website. It is not directed to children under 13, and we do not knowingly collect personal information from a child under 13. Where local law sets a higher age for independent consent, a younger user should use the site only with the involvement of a parent or legal guardian.
Education, grade, math or other student-friendly calculators do not require a child to provide a name, school, account credential or precise date of birth. Parents and guardians should supervise use and prevent children from posting personal information in public comments or messages.
If you believe a child has submitted personal information to 1Dollars, email contact@1dollars.org so we can review the situation and take appropriate action.
15. Third-party websites, services and social platforms
1Dollars may link to banks, lenders, insurers, investment services, government agencies, research sources, merchants, social platforms and other external websites. A link is not an instruction to provide information and does not make 1Dollars responsible for the external site's privacy, security, availability, products or content.
Before sending financial, health, identity or account information to another organization, verify the domain, review its privacy policy and confirm that you are using an official and secure service. Social-media interactions are governed by the policy and settings of the relevant platform.
16. Policy changes and privacy contact
We may update this policy when the website, calculator features, providers, advertising configuration, legal requirements or internal practices change. The current version will be posted on this URL with a revised last-updated date. When appropriate, a material change may also be highlighted through a website or consent notice.
For a privacy question, concern or request, contact:

The English version of this policy is the primary version unless a translated version expressly states otherwise.
Frequently asked privacy questions
Do I need an account to use 1Dollars calculators?
Most public calculators can be used without a 1Dollars account, name, email address or payment information. A future optional feature may have a separate notice if it requires additional information.
Does 1Dollars store every value I enter into a calculator?
Many calculators process values in the current browser page and do not create an account record. Some tools may use local browser storage or offer copy, print, history or download functions. Technical and interaction data may still be processed by platform, analytics, security or advertising technologies.
What information should I avoid entering?
Do not enter passwords, one-time passwords, complete bank or card details, government identification numbers, account credentials, precise addresses, private keys, complete medical records or another person's confidential information.
Why does 1Dollars use cookies?
Cookies and similar technologies may support Blogger page delivery, security, consent records, analytics, advertising, affiliate attribution and embedded features. The exact set can vary by page, region, provider and consent choice.
Does 1Dollars sell personal information?
1Dollars does not sell personal information directly for cash. Some privacy laws may nevertheless classify certain advertising or analytics activities as sale, sharing or targeted advertising, and eligible users may opt out where applicable.
How can I limit personalized advertising?
Use the site's consent controls where available, manage Google Ads Settings, use participating-industry opt-out tools, clear browser cookies or enable a legally recognized browser opt-out signal where supported.
Does Microsoft Clarity record everything I type?
When Microsoft Clarity is active, it supports behavioral analytics such as clicks, scrolling, navigation, heatmaps and session recordings. Masking or exclusion settings may apply, but you should never rely on masking and should not type sensitive information into a calculator, form or public comment.
Are Blogger comments private?
