Privacy proof for Pomodoro Study Timer

This tool processes files in your browser. Open DevTools → Network while you run it: your document is not uploaded. After one online visit, many tools keep working with Airplane Mode on (libraries cached locally).

Each tool runs entirely with JavaScript already loaded in this page — PDF tools via pdf-lib and pdf.js, image tools via the browser's native Canvas API, and everything else with plain JavaScript. Your files or input are read into browser memory, processed, and handed back as a download or copyable result. This page itself is served by a small Laravel route; Laravel never sees your files either. The only backend in use is Supabase, and only for two optional things: signing in with a magic link, and — only if you're signed in — a log of which tool you ran and when. Honest limits worth knowing: Compress PDF flattens each page to a re-encoded image (great for scans, not ideal if you need selectable text after); HEIC conversion uses a small on-demand converter when the browser cannot decode HEIC natively (Safari often works without it); Fill PDF Form is best-effort for simple AcroForm fields, not a full Adobe Forms replacement; and Word/Excel/PowerPoint ⇄ PDF genuinely needs a server-side engine, so it isn't included — this build only ships tools that can honestly run client-side.

What is the Pomodoro Technique?

A time-management method of alternating focused work sessions (traditionally 25 minutes) with short breaks (traditionally 5 minutes), repeated for a set number of cycles — meant to make sustained focus easier to maintain.

Can I change the work and break lengths?

Yes — set any work minutes, break minutes, and number of cycles before starting; the classic 25/5 split is just the default.

Does it keep running if I switch browser tabs?

Yes — the countdown continues in the background as long as this tab stays open; switching tabs or apps doesn't pause it.

Can I pause and resume?

Yes — the same button toggles between Pause and Resume without losing your place in the current cycle.

What happens after all the cycles finish?

The timer stops and shows a completion message — it doesn't loop indefinitely or restart on its own.

Does it send a notification when a phase ends?

No system or browser push notification — the on-screen display updates the moment a work or break phase ends, so keep the tab visible or check back near the end of a session.

Does it save my session history or streaks?

No — this is a simple, private timer with no accounts, tracking, or saved history. Closing the tab resets it.

Is anything about my usage sent anywhere?

No — the timer runs entirely in your browser with plain JavaScript; nothing is transmitted.

Is this really free, and is there a file size limit?

Yes — no account, no paywall. Since processing happens in your browser's memory rather than uploading anywhere, the practical limit is your device's available RAM, not a server quota. Very large files (500+ pages) may run slower, especially for Compress and PDF→JPG.

Does anything about my file get sent anywhere?

No. Every tool runs with pdf-lib/pdf.js loaded in this page; your file is read into browser memory and never leaves it. The only network call this app makes for your account is Supabase auth — and that only stores which tool you ran and when, never file content.

Why isn't Word/Excel/PowerPoint → PDF included?

Converting Office formats accurately needs a real rendering engine (what Word or LibreOffice use internally) — no browser library does this reliably. Rather than ship a broken version, it's left out.

Does TechDriven Tools have OCR (text recognition)?

Yes — OCR PDF recognizes text in scanned or photographed pages using Tesseract.js, running entirely on your device, and gives you a searchable PDF or a plain text file. Nothing is uploaded for this either.

Can I use this without an internet connection?

Once the page and its libraries have loaded once, yes — the tools themselves need no network access. Signing in and viewing history do require a connection, since those talk to Supabase.

What happens to the "history" if I sign in?

Only a row per tool run — the tool's name and a timestamp. No filename, no file content, ever. You can see the full list any time via the History button.

Are the non-PDF utilities (password generator, JSON formatter, etc.) private too?

Yes — same rule as the PDF tools. Word Counter, Case Converter, Password Generator, UUID Generator, Base64, Hash Generator, JSON Formatter and JWT Decoder all run with plain JavaScript already loaded in this page; nothing you type or paste is sent anywhere.

Why use Pomodoro Study Timer

  • Structure a study or work session into focused blocks instead of one open-ended stretch.
  • Build in real breaks that a phone timer or mental estimate tends to skip.
  • Try the Pomodoro Technique without installing a dedicated app.
  • Time a fixed number of focus rounds for a study session, sprint, or task block.

How it works

Set a work length, a break length, and a number of cycles, then start the timer. It counts down through each work phase, automatically switches to a break, and repeats for the number of cycles you set — all running as plain JavaScript in this tab, with no server, account, or app involved.

The Pomodoro Technique

Named after a tomato-shaped kitchen timer, the technique alternates focused work intervals with short breaks on the idea that sustained attention holds up better in bounded chunks than in one long, undefined session. The traditional split is 25 minutes of work to 5 minutes of break, repeated four times before a longer break — but there's nothing special about those exact numbers; adjust them to whatever rhythm actually works for you.

Who Pomodoro Study Timer is for

  • A desktop suite is overkill for a one-page or one-photo job.
  • You want a second opinion after another converter produced a weird output.
  • You need a result now and do not want another account wall.
  • The file or text is sensitive enough that uploading feels wrong.

Recommended workflow

Enter values carefully with units → double-check the formula assumptions → treat the result as a study aid unless your course says otherwise.

  1. Open Pomodoro Study Timer (also available from category hubs and ⌘K).
  2. Use the labeled fields or dropzone — options match what Pomodoro Study Timer actually does.
  3. Run the tool and wait for local progress to finish.
  4. Download or copy the result, then verify on the device where you will share it.

Tips that improve results

  • Rename the output with date + purpose before you attach it to email.
  • On phones, plug in power for large PDFs, videos, or spreadsheets.
  • Prefer UTF-8 text for developer converters; weird encodings cause most “broken” results.
  • Start with a non-sensitive sample so you learn the options before the real file.
  • Change one setting at a time when you are comparing quality or layout.
  • Keep the original until stakeholders accept the download.

Common mistakes with Pomodoro Study Timer

  • Expecting Pomodoro Study Timer to replace a full desktop suite for every edge-case format.
  • Skipping a sample check and discovering a bad export after the original was deleted.
  • Chaining many lossy image/PDF steps when one careful pass would have been enough.
  • Using a public computer without clearing downloads afterward.

Privacy model

Processing for Pomodoro Study Timer is designed to stay in the browser. Laravel serves the page; it does not receive your file bytes for conversion. Optional Supabase auth only stores which tool you ran and when — never filenames or contents.
