This policy describes data processing by the Streetlifting Calculator. Last updated: 9 October 2026.
2. Calculations in your browser
Bodyweight, added or bar weight and rep count are processed directly in your browser for calculations. The application does not transmit these inputs or results to us or a server. There are no user accounts or server-side training profiles.
Inputs remain only in the open page’s memory. Reloading restores the default values. We cannot access training values stored only in your browser.
3. No persistent browser storage
The application does not save inputs or language in localStorage, sessionStorage or cookies. Inputs remain only in the open page’s memory and reset on reload. The language comes from the page URL; the browser language is used when opening the root address.
Calculator values and the storage preference saved by earlier versions are removed from localStorage on the next visit to this version. Other browser data is not affected.
4. Hosting and delivery through Cloudflare
The website is publicly available at https://streetliftingcalculator.com. We use Cloudflare, Inc., 101 Townsend Street, San Francisco, CA 94107, USA, to host and deliver the website.
Requests served through Cloudflare involve technical request data, particularly IP address, requested URL, timestamp, browser information and, where applicable, referrer, response status and security events. The purpose is delivery and secure operation. The basis for processing initiated by us is Article 6 (1) (f) GDPR; our interest is reliable and secure provision of the calculator.
Cloudflare’s Data Processing Addendum governs processing on behalf of customers. Annex 1 defines the retention criterion as the earlier of termination of the agreement or the end of processing needed to fulfil it. For data processed by Cloudflare as a controller, retention depends on the relevant purpose and legal obligations under its privacy policy. The linked documents describe these criteria; they do not establish a single deletion period applicable to all technical request and security data.
5. International processing by the host
Cloudflare operates a global network. Technical data may be processed outside the EEA, particularly in the United States. Its DPA provides for the EU–US Data Privacy Framework for covered US transfers and, particularly, EU Standard Contractual Clauses for other restricted transfers. Safeguards are described in the linked DPA; you may also request information through our contact address.
6. Cookies, tracking and external content
The current application sets no cookies of its own and includes no analytics or advertising scripts. Facebook Pixel, Google Analytics, Google Tag Manager and embedded YouTube videos are not used. Fonts and symbols are not loaded from external font or icon services. The application does not use persistent browser storage.
On pages containing contact details, Cloudflare obfuscates our email address to make automated harvesting for spam more difficult. A Cloudflare script loaded through the same website address makes it readable in your browser. Loading it involves the technical data processing described in section 4. The basis is Article 6 (1) (f) GDPR; our interest is protecting the contact address from spam. This feature is not used to analyse your behaviour.
External links are accessed only when you open them. The privacy information of the respective provider applies on linked websites.
7. Email and telephone contact
When you contact us, we process the contact details you provide, your message and any attachments to handle and answer your request. Telephone requests may include your phone number and any notes we make. Providing additional information is voluntary; without a means to contact you, we may be unable to answer written requests. We do not use enquiries for advertising.
The legal basis is Article 6 (1) (f) GDPR. Our legitimate interest is responding to enquiries about this hobby project. Completed enquiries and related notes are deleted no later than six months after resolution. Where statutory retention requirements apply or retention is needed for a specific legal dispute, necessary correspondence remains until that obligation or proceeding ends.
Email is received and answered directly through Gmail without another forwarding service. The provider for the EEA is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Google processes messages, attachments and technical delivery information under its service terms and privacy information. Merely visiting our website does not connect your browser to Gmail.
Google may process data outside the EEA, particularly through Google LLC in the United States. Google identifies the EU–US Data Privacy Framework and Standard Contractual Clauses for other necessary transfers among its safeguards. Google’s processing and technical deletion are additionally described in the links below. Our six-month period refers to deletion from the mailbox we manage; we do not control the deletion periods of all Google logs or backup copies.
8. Your rights
Subject to the applicable legal conditions, you may request access, rectification, erasure, restriction and portability. You may withdraw consent at any time for future processing. Send requests through the contact details in section 1. Calculator values in memory reset on reload.
Objection: You may object to processing based on Article 6 (1) (f) GDPR on grounds relating to your particular situation.
You may complain to a data protection supervisory authority, particularly in your habitual residence, place of work or the location of an alleged infringement. The authority for North Rhine-Westphalia is the State Commissioner for Data Protection and Freedom of Information North Rhine-Westphalia.
We do not make solely automated decisions producing legal or similarly significant effects. The calculator only provides a training estimate.
9. Changes
We update this policy when features, providers or data processing change. Appropriate consent will be obtained before any processing for new purposes requiring consent.
