Cookie Policy

Last updated: August 6, 2026

This Cookie Policy explains what cookies and similar technologies OneDevToolkit uses. It is written for clarity and is not legal advice. For a fuller picture of personal data, see our Privacy Policy and Terms & Conditions.

1. Tool data stays in your browser

OneDevToolkit’s utilities are built to run in your browser. When you format JSON, compress an image, test a regex, or work with a PDF, that content is processed on your device.

We do not upload, store, or process those tool inputs on OneDevToolkit servers for normal tool execution. Temporary results, drafts, and preferences that a tool needs between steps are kept locally using browser technologies such as:

• Local Storage — persists until you clear site data
• Session Storage — usually cleared when the tab or browser session ends
• IndexedDB — used for larger local items such as Vault entries

You control this data. If you clear your browser’s cookies, cache, or site storage for onedevtoolkit.com, locally saved preferences, favourites, recipes, vault items, and similar information may be permanently removed from that browser. We cannot restore data that only ever lived on your device.

2. What are cookies and similar technologies?

Cookies are small text files a website can store in your browser. Similar technologies include local storage, session storage, and pixels used by analytics providers.

Some cookies are set by OneDevToolkit (first-party). Others may be set by services we load, such as Google Analytics or Google reCAPTCHA (third-party), when those features run.

3. Cookie categories — what we use

Websites often group cookies into four types. Here is how that maps to OneDevToolkit today:

Essential cookies & storage — Used

Needed for the site to work securely and reliably. Examples include remembering that the page loaded correctly, supporting basic navigation, and (when you sign in) keeping an authentication session active. Without these, parts of the site may not function.

Functional cookies & storage — Used

Remember choices you make so the toolkit feels consistent. On OneDevToolkit this is mainly browser storage, not advertising cookies. Examples include:

• th-theme — light or dark mode
• th-favs / th-recent — favourite and recent tools
• th-recipes and related keys — private recipe workflows on your device
• th-tool-usage / history helpers — local usage hints for a better UI
• IndexedDB vault store — encrypted vault items kept only on your device
• Session keys such as recipe hand-offs between pages

These stay under your control on your browser. Clearing site data removes them.

Analytics cookies — Used

We use Google Tag Manager (container GTM-NKS29HFG) and Google Analytics 4 (measurement ID G-6PRCK6PN01) to understand how visitors use the site — for example which pages are popular, approximate location, device type, and referral source.

Google may set cookies such as _ga, _gid, and related measurement cookies. Analytics helps us improve the toolkit. It is not used to read the text or files you paste into tools.

You can limit analytics with browser settings, privacy extensions, or Google’s Analytics Opt-out Browser Add-on. See also Google’s Privacy Policy.

Marketing / advertising cookies — Not used

OneDevToolkit does not currently use advertising networks, retargeting pixels, or marketing cookies to sell ads or build advertising profiles from your tool usage. We do not sell, share, or store your personal browsing or tool data for advertising purposes.

We also do not operate an email newsletter platform (such as Mailchimp) that would place marketing cookies on this site.

4. Other technologies you may encounter

Google reCAPTCHA (contact form)

When you submit our contact form, Google reCAPTCHA v3 helps block spam. Google may use cookies or similar storage as part of that check. If you prefer not to use reCAPTCHA, you can email us directly at support@onedevtoolkit.com instead of using the form.

Account session cookies

If you create an optional account and sign in, our authentication API may set a session cookie so you stay logged in. That cookie is for account features (such as syncing favourites). It does not contain the contents of files you process in tools.

Hosting and delivery

The site is hosted on Netlify. Like most hosts, the network path to reach the site may involve standard connection logs on infrastructure providers. That is separate from storing your tool inputs. We do not currently run a Cloudflare cookie banner as part of the core toolkit, and we do not claim Cloudflare WAF cookies unless that product is later enabled in front of the domain.

Fonts and CDN scripts

We load fonts and some libraries from trusted CDNs (for example Google Fonts or jsDelivr). Those requests are for delivering assets, not for reading your tool contents.

5. What we do not do with cookies

• We do not use cookies to upload your tool paste/files to OneDevToolkit servers
• We do not sell personal data for advertising
• We do not place third-party advertising cookies with the core toolkit
• We do not use Mailchimp or similar newsletter cookies on this site today

6. How to manage, block, or delete cookies

You can control cookies and site storage in your browser. Steps vary by browser, but typically you can:

• Open Settings → Privacy / Security → Cookies and site data
• Remove cookies and storage for onedevtoolkit.com
• Block third-party cookies, or block cookies from specific sites
• Use private / incognito windows (storage is often discarded when the window closes)

Useful starting points:

• Google Chrome
• Mozilla Firefox
• Apple Safari
• Microsoft Edge

Please note: blocking essential or functional storage may reset your theme, favourites, recipes, or vault on that browser. Blocking analytics cookies does not stop you from using the tools.

7. Changes to this Cookie Policy

We may update this page when we add features, change analytics, or adjust how storage works. When we make material changes, we will revise the “Last updated” date at the top. Please review this page occasionally so you stay informed. Continued use of OneDevToolkit after an update means you understand the revised Cookie Policy.
