Privacy Policy

Last updated: November 11, 2026

This policy is published at https://nativetone.fuyun.one/privacy.html

Summary

• NativeTone only reads the text you ask it to rewrite, and only when you ask.
• That text is sent to DeepSeek's API to generate the rewrites.
• We do not store your drafts or the rewrites.
• We store only an anonymous install ID with a monthly usage count (and, if you upgrade, your subscription status).
• We do not sell your data or use it for advertising.

What the extension accesses

The NativeTone Chrome extension runs only on reddit.com, linkedin.com, x.com / twitter.com and mail.google.com. When you press the NativeTone shortcut (or click the toolbar button), it reads:

• the text in the reply or compose box you are typing in, or the part of it you selected; and
• the website's hostname (for example, www.reddit.com) so it can match that platform's tone.

It does not read your feed, messages, contacts, other page content or browsing history. When you click Insert, it writes the chosen rewrite back into that same box.

What we send and to whom

The text and hostname are sent over HTTPS to our server (nativetone-api.fuyun.one, hosted on Cloudflare), which forwards the text to the DeepSeek API (operated by DeepSeek) to generate rewrites. DeepSeek processes that text under its own terms and privacy policy, which describe how it handles and retains API data: see the DeepSeek Privacy Policy and the DeepSeek Open Platform Terms of Service.

The web tool on this site works the same way with the text you paste.

What we store

• Drafts and rewrites: not stored. Our server does not write draft text to logs or databases.
• Anonymous install ID: a random ID created by the extension (or your browser for the web tool), used to count rewrites.
• Usage counts: number of rewrites per install ID per month, kept for about 40 days.
• Operational logs: request metadata such as platform, text length, timing and errors — never the text itself.
• Settings: your shortcut, US/UK English preference and server URL are stored in your browser (Chrome storage).

Payments

If you upgrade to Pro, payment is handled by a third-party payment provider. We never see or store your card details. We receive your email, plan and subscription status to unlock Pro.

Who can use NativeTone

NativeTone is not directed to children under 13 (or the minimum age in your country).

Your choices

• Uninstall the extension at any time; its local settings are removed with it.
• To delete your usage count or subscription data, email support@fuyun.one with your install ID (shown on the extension's Options page).

Changes

We'll update this page and its date if anything changes.
