Privacy Policy
Your data is your business. We've built DevToolHub to ensure it stays that way.
Transparency Statement
As of 2026, DevToolHub and its affiliated projects are managed under a privacy-first mandate. Any legacy metadata or historical records associated with our domains prior to 2026 do not reflect our current operational standards. We operate on a 100% client-side processing model: no tracking, and no server ever receives, stores, or logs the data you type or upload into a tool. Two tools — the Resume Builder and Cover Letter Generator — do save what you type to your own deviceso your draft isn't lost between visits. That's local, not server-side, and Section 2 below explains exactly what is stored and how to clear it.
1. The "Zero Data" Principle
Unlike traditional web applications that process user input on a central server, DevToolHub operates on a client-side execution model. When you paste JSON into our formatter or encode a string to Base64, the computation happens entirely within your browser's local memory space using JavaScript.
This approach effectively places an "Air Gap" between your sensitive data and our infrastructure: whatever you paste, type, or upload into a DevToolHub tool is never transmitted over the internet to us, and we have no server-side record of it. For most tools, that data also never leaves your browser's in-memory sandbox at all — it exists only while the tab is open. Two tools are a deliberate, disclosed exception to the "memory only" part: see Section 2 for exactly what they store on your device and why.
No Server Processing
We do not have a backend database for your tool inputs. Your data never touches our disks or logs.
No Tracking
We do not use invasive tracking pixels, fingerprinting scripts, or third-party behavioral analytics.
2. Information Collection & Usage
Our primary goal is to collect the absolute minimum amount of information required to serve the application files to your browser.
- Standard Server Logs: Our web hosting provider may log standard metadata such as your IP address, browser user-agent, and the timestamp of your request. This data is used exclusively for security monitoring (e.g., detecting DDoS attacks or malicious scraping) and is never correlated with the data you process inside our tools.
- LocalStorage — UI preferences: We do not use persistent cookies for tracking. We use your browser's
localStorageto remember your Dark/Light mode choice across visits. That's the only UI preference we currently persist this way.
2a. What the Resume Builder & Cover Letter Generator Store
These two tools are the one place on DevToolHub where your input is saved to your device between visits, so it's worth its own section rather than a single bullet point.
- What is stored:everything you enter into either tool — your name, job title, email, phone, location, links, work history, education, skills, certifications, projects, languages, and your cover letter text. It's saved together, under one browser storage key, so information you enter in one tool is available in the other.
- Which tools: only the Resume Builder and Cover Letter Generator. No other tool on DevToolHub saves your input between visits — everything else processes data in memory only and forgets it the moment you refresh or close the tab.
- Where it's stored: in your browser's
localStorage, on your own device only, as plain (unencrypted) text. - Is it sent to a server? No. We do not transmit, upload, or have any server-side copy of this data at any point — not while you type, not when you export a PDF, and not in the background. The PDF itself is generated locally in your browser and downloaded directly to your device.
- Does it persist after you close the browser?Yes. Unlike the in-memory processing used by every other tool, this data is written to disk-backed storage and will still be there the next time you open the page — that's the intended behavior, so your draft survives a reload or an accidental tab close.
- How to clear it:both tools show a "Clear my data" control that permanently deletes this record from your browser. You can also clear it yourself through your browser's site-data settings, or it will be removed automatically if you clear your browser's local storage.
- Limitations worth knowing: because this data isn't encrypted, anything else that can run script on the page in your browser — for example, a malicious browser extension — could in principle read it, the same as with any other website's
localStorage. It is also local to one browser on one device: it won't follow you to a different browser or computer, and clearing your browser's storage (or using private/incognito mode) will erase it. If you're on a shared or public computer, use the "Clear my data" control when you're done.
3. Verification & Zero-Trust
We believe in "Verify, Don't Trust."
Because we use standard, transparent Web APIs, any developer can verify our claims by opening the "Network" tab in their browser's Developer Tools (F12). You will observe that after the initial static assets are downloaded, no network requests are initiated when you click "Format," "Encode," or "Decode."
Our commitment to privacy is not just a legal policy—it is the foundational engineering architecture of the entire platform. By removing the server from the data-processing equation, we remove the single largest point of failure for data privacy.
4. Technical Data Isolation & Sandbox Integrity
The security of your data on DevToolHub is not just a matter of policy, but a matter of browser-level hardware enforcement. Modern web browsers implement what is known as the Same-Origin Policy (SOP) and site-level isolation. Our tools are built to work strictly within this secure execution environment.
Browser Site Isolation
Modern browsers isolate each site into its own process, which is a standard browser security feature — not something DevToolHub adds on top. It means another tab or site can't directly reach into DevToolHub's memory or storage, and vice versa.
Memory-Only, With One Exception
Most tools perform all string manipulation in volatile RAM only: once the processing is complete and you close or refresh the tab, that input is gone from your device. The Resume Builder and Cover Letter Generator are the exception — as described in Section 2a, they intentionally write your draft to disk-backed localStorage so it survives a reload, until you clear it.
5. Jurisdictional & Regulatory Alignment
While many privacy policies are designed to navigate the legal complexities of data transfer across borders, DevToolHub avoids this issue entirely by not transferring data.
We are not a compliance product, and using DevToolHub does not, by itself, make you HIPAA, SOC 2, GDPR, or CCPA compliant — none of those frameworks can be satisfied by a client-side tool alone; they require a legal and organizational program (policies, audits, agreements, and in HIPAA's case a signed Business Associate Agreement) that DevToolHub does not provide.
What we can tell you factually: for the tools described above as "memory only," your data is never transmitted to us and we hold no server-side copy of it, which removes network transmission and server-side storage as a risk factor for that data. For the Resume Builder and Cover Letter Generator, the same "never transmitted to us" fact holds, but the data isretained locally on your device (Section 2a) — so if your use case has retention or on-device-storage requirements, that's the detail to evaluate against your own policy. If you operate under HIPAA, GDPR, SOC 2, or a similar framework, please confirm with your own compliance or legal team whether that is sufficient for your situation — we are not in a position to make that determination for you.
