Devbelt privacy policy
Last updated: 29 August 2026
Devbelt is a browser extension that formats, decodes and inspects text you paste into it. Nothing you paste ever leaves your computer. The only time Devbelt talks to a network at all is to check whether you have bought Pro.
What you paste
Text you paste into a tool is processed in the extension popup on your own machine and then discarded. Every one of the twenty tools runs locally — the JSON formatter, the JWT decoder, the hash generator and the rest never send your input anywhere, and they work with your network unplugged.
If "Remember what I typed" is on (it is by default), the last input for each tool is written to Chrome's local extension storage on this device so the popup still has it next time you open it. That data:
- never leaves your computer;
- is not synced to your Google account;
- can be wiped at any time with Settings → Stored data → Clear everything, or by turning the setting off, which deletes the saved drafts immediately.
Payments, and the one network connection
Devbelt Pro is sold through ExtensionPay (extensionpay.com), which processes payments with Stripe. This is the only part of Devbelt that uses the network, and it is the only place any personal data is involved.
When you start a free trial, buy Pro, or log in to restore a purchase:
- You give ExtensionPay your email address, on their page, not in Devbelt.
- ExtensionPay creates an anonymous installation identifier for your copy of the extension so it can tell whether that copy has paid.
- Devbelt asks ExtensionPay "has this installation paid?" when the popup opens, and stores the answer — your paid/trial status and the email on the account — in local extension storage so the tools still unlock when you are offline.
- Card details go directly to Stripe. Devbelt never sees, receives or stores them, and neither the extension nor its author has access to your card.
ExtensionPay and Stripe handle that data under their own privacy policies:
- ExtensionPay — https://extensionpay.com/privacy
- Stripe — https://stripe.com/privacy
No text you paste into a tool is ever included in any of this. The payment check sends only the installation identifier; it carries no tool input, no filenames and no browsing information.
If you never buy and never start a trial, Devbelt makes no network requests at all.
Licence keys, if you have one
Devbelt also accepts an offline licence key, which is verified with a signature check against a public key inside the extension. That path involves no network connection and no account whatsoever — the key is never transmitted anywhere.
What is stored on your device
Using the storage permission — the only permission Devbelt requests — the extension keeps:
- your preferences (theme, line wrapping, indent size, remember-input on or off);
- your pinned and recently used tools;
- the last input per tool, if you leave that setting on;
- your paid/trial status and the email address on your ExtensionPay account, or your offline licence key if you use one.
Removing the extension removes all of it.
Permissions
| Permission | Why |
|---|---|
storage | To keep the preferences, pins, drafts and payment status listed above on this device. |
Access to extensionpay.com | Devbelt runs a script on extensionpay.com so that finishing a purchase there can unlock Pro here. It has no access to any other website. |
Devbelt requests no other host access. It cannot read the pages you visit, your tabs, your history, your cookies or your clipboard contents. It only sees what you paste into its own window, and the payment page you are already on.
Analytics
None. Devbelt contains no analytics, no telemetry, no crash reporting, no advertising and no third-party trackers of any kind. Nothing you do inside the extension is measured or reported.
Third parties
Beyond ExtensionPay and Stripe handling payments as described above, Devbelt bundles no third-party services, loads no remote scripts, fonts or stylesheets, and shares data with no one. Your data is never sold, and never transferred to anyone for advertising or any purpose unrelated to running the extension.
Children
Devbelt is a developer tool and is not directed at children. It collects no personal information from anyone, of any age, beyond the purchase email described above.
Changes
If this policy ever changes, the updated version will be published at this URL with a new date at the top, and material changes will be noted in the extension's changelog.
