This policy explains how ti84calculators.online, run under the name TI-84 Calculator, handles information. The short version: you can use every tool without an account, and we do not run analytics, ads, or tracking scripts.
Information stored in your browser
The calculators save your history, lists, functions, inputs, and settings in your browser's local storage, so your work is still there next time. This data stays on your device. It is never sent to us.
To delete it, use Reset calculator on the homepage or clear this site's data in your browser settings. The site works normally if your browser blocks storage.
Information you send us
If you email us, we receive your email address and your message. We use them only to reply and to fix any problem you report. We do not sell them or add you to a mailing list, and we delete messages once they are no longer needed.
Hosting and server logs
The site is hosted on Cloudflare. To deliver pages and protect the site from attacks, Cloudflare processes technical data such as your IP address, browser type, and the pages you request. Cloudflare may also set a strictly necessary security cookie. See the Cloudflare privacy policy for details.
Cookies and third parties
We do not set cookies of our own. Fonts and scripts load from this site, not from outside services. Links to other sites, such as official exam policies, follow those sites' own privacy policies.
If we ever add analytics or advertising, we will update this policy before they go live and describe what they collect.
Children's privacy
Many of our visitors are students. We do not knowingly collect personal information from children under 13. Children under 13 should ask a parent or guardian before emailing us. If we learn we have received a message from a child under 13, we will delete it.
Your choices
You can ask us to delete any message you sent or to tell you what we hold about you. Depending on where you live, laws such as the GDPR or the CCPA may give you more rights, and we will honor those requests.
