What happens to your data

1. What Phantaslate does not collect

Phantaslate does not collect, request, or store:

• Names, email addresses, or any account identifiers
• Passwords or authentication credentials
• Payment or financial information
• Browsing history or the list of pages you visit
• Clicks, scrolling, keystrokes, mouse position, or other behavioural telemetry
• Device fingerprints
• Health, biometric, or demographic information

There is no analytics SDK, no advertising SDK, and no third-party tracking script in the extension.

2. What is transmitted, and to whom

Phantaslate only transmits text that you explicitly submit for translation — by typing or pasting it into the panel and pressing Translate. Text on a page you are merely viewing is never read or transmitted.

When you press Translate, the following happens:

• Your submitted text, along with your chosen source and target languages, is sent over HTTPS to the Phantaslate relay at api.phantaslate.com.
• The relay forwards that text to DeepSeek, a third-party machine-translation provider, in order to produce the translation.
• The translation is returned through the relay to your browser and displayed in the panel.
• The relay holds the text only in memory for the duration of the request. Once the response is returned, it is gone. Nothing is written to disk, to a database, or to a log.

The DeepSeek disclosure

We state this plainly because a privacy promise that quietly omits it would not be worth much. What Phantaslate controls is everything on its own side of that boundary: no retention, no logging, no linkage between your text and any identifier.

Please review DeepSeek's own privacy documentation if this matters to your use case. If you handle text that must never reach a third-party API, Phantaslate — like every hosted translation service — is not the right tool for it.

Other infrastructure providers

• Render hosts the relay. As with any hosting provider, Render may generate transient operational and network-level logs as part of running the service. Phantaslate does not create, request, or retain application logs of translation content.
• Cloudflare provides DNS resolution for the phantaslate.com domain. The api subdomain is configured as DNS-only, meaning Cloudflare resolves the address but does not proxy or inspect the traffic itself.

3. Abuse prevention

To keep a free, account-free service usable, Phantaslate applies a daily usage cap — a baseline of 20,000 characters per day, which may be reduced during periods of high demand or cost pressure.

Enforcing a limit without accounts requires some way to distinguish one user from another. Phantaslate does this in the least identifying way we could design:

• Your IP address is combined with a rotating salt and hashed. The resulting hash is used as a short-lived counter key. The raw IP address is not stored, and because the salt rotates, hashes cannot be correlated across time periods.
• A short-lived, randomly generated install token accompanies requests from your browser. It is not tied to your identity and carries no personal information.

These values exist solely to count usage against a cap. They are not used to build a profile, are not linked to translation content, and are not shared.

Because an IP address is processed — even momentarily, and even in hashed form — we disclose "Location" in the Chrome Web Store data usage form. We would rather over-disclose than have a technically true claim mislead you.

4. Data stored on your device

Phantaslate stores a small number of preferences locally using chrome.storage.local. These never leave your browser and are never sent to the relay:

Stored value	Purpose
Panel position and size	Keeps the panel where you left it
Relay URL	Allows you to point the extension at a different relay
"Remember last used languages" preference	Opt-in only; off by default
Last used language pair	Stored only if you enable the option above

Translation text and results are never written to storage. Closing the panel clears its contents.

You can remove all locally stored data at any time by uninstalling the extension, or by clearing the extension's storage from your browser's settings.

5. Permissions and why they are needed

Permission	Why it is required
activeTab	Opens and focuses the panel on the page you are currently viewing when you click the extension icon
scripting	Injects the translation panel into the page so you can translate without leaving it
storage	Saves the local preferences listed in section 4
clipboardWrite	Powers the panel's Copy button, on click only
Host permission — page access	Required to display the panel on the pages you visit
Host permission — api.phantaslate.com	Required to send submitted text to the relay and receive the translation

No permission is used for any purpose beyond the one stated above.

6. Data retention

Data	Retention
Submitted text	Held in memory for the duration of the request only
Translation results	Not retained by the relay
Usage counters (salted hashes)	Short-lived; expire with the rate-limit window and salt rotation
Local preferences	Kept on your device until you clear or uninstall

Phantaslate has no database of user content. There is no archive to search, no history to export, and nothing to hand over in response to a request — because nothing is kept.

7. Your rights

Because Phantaslate does not hold personal data associated with you, there is nothing to access, correct, export, or delete on our side. There is no account to close.

If you are in a jurisdiction with data protection rights such as the GDPR or CCPA and believe personal data of yours has nonetheless been processed, you are welcome to contact us using the details in section 10.

Phantaslate does not sell personal information, and does not share it for cross-context behavioural advertising.

8. Children

Phantaslate is not directed at children and does not knowingly collect information from them. Since no personal information is collected from anyone, this holds generally.

9. Verification and changes

Phantaslate is open source. Every claim in this document can be checked against the source code, including the relay:

github.com/October34th/phantaslate

If this policy changes, the revised version will be published at the same URL with an updated effective date, and material changes will be noted in the repository's release notes. Continued use of the extension after a change indicates acceptance of the revised policy.
