How we handle cookies, ads, and data
Last updated: June 27, 2026
ToneSynth (tonesynth.com) is a free, browser-based tone and waveform generator, part of the Audio Tools Network. You can reach us at contact@tonesynth.com. This policy explains what information is collected when you use the site and how it is used.
All tones are generated locally in your browser using the Web Audio API. The audio is never recorded, uploaded, or transmitted to us or anyone else. We do not require an account, and we do not collect names, email addresses, or other personal details unless you choose to email us directly.
ToneSynth uses cookies and similar technologies to run analytics and to serve advertising. Cookies are small files stored by your browser. You can block or delete them in your browser settings, though some features may behave differently if you do.
We display ads through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the internet.
Other third-party ad vendors or ad networks may also use cookies and similar identifiers to measure and serve advertising on this site.
We use Google Analytics (GA4) to understand anonymous, aggregate usage, such as which pages are visited and which browsers are used. This helps us improve the tool. Google's handling of analytics data is described in the Google Privacy Policy.
ToneSynth participates in the Amazon Associates program and may include other affiliate links. If you click an affiliate link and make a purchase, we may earn a commission at no extra cost to you. This helps keep the site free.
We do not sell your personal information. We do not collect audio data or account data, and we do not share personal information beyond what the advertising and analytics services described above process to function.
If you are in the European Economic Area, the United Kingdom, or California, you have rights over your personal data, including access, correction, and deletion, and you may opt out of personalized advertising using the links above. To exercise any of these rights, contact us at contact@tonesynth.com.
We may update this policy from time to time. When we do, we'll revise the "last updated" date above. Continued use of the site after changes means you accept the revised policy.
