Privacy Policy

Scope

This policy explains how StudyKit handles information when you visit this site or use one of its browser-based tools. StudyKit does not require an account for the tools.

This policy covers studykittools.com only. StudyKit also operates a separate website at courcertificate.studykittools.com, which lists courses and certificates offered by other organisations. It is run by the same StudyKit operator on separate systems, and it has its own privacy policy. The two are kept apart on purpose: this site is funded by advertising and holds no personal data beyond server logs, whereas that site carries no advertising and instead may hold account information. One notice describing both would be vague exactly where it needs to be specific. The same operator and the same contact addresses apply to both.

Text entered into tools

Most of the tools are designed to perform calculations and file processing in your browser. Four of them are different, because a browser cannot do that work on its own: the Word to PDF converter, the Image Background Remover, the AI Text Humanizer, and the Flashcards card maker. Each is set out in full below. For every other tool, StudyKit does not intentionally receive or store the text, images, or captured frames you provide as part of a tool task. For those four, your input is sent to the server that hosts this site so that it can be processed, is not passed on to any third party, and is deleted as described in each section. None of them is used to train a model. Browser extensions, security software, your browser, and hosting providers may process data as part of normal operation, so do not enter information you are not authorized to share.

Documents, images, and screenshots

The image redaction tool works entirely in your browser, and an image chosen for it is not intentionally uploaded to the server that hosts this site. The Word to PDF tool is different: it converts your document on the server that hosts this site using LibreOffice, because no web browser can reproduce a Word page layout. When you choose a document for that tool, the file is uploaded over your connection, converted, and the uploaded document is deleted from the server as soon as the conversion finishes, and the generated PDF as soon as the download is delivered, or within 45 minutes if it is never collected. The screenshot tool uses your browser’s permission prompt to capture a tab, window, or screen; captured frames remain in the current page until you clear them, reload, or close the tab. The image tools — compressing, resizing, changing aspect ratio, converting, blurring, picking a colour, and adding a watermark — all work this way: an image you choose is read by your browser, and it is not sent to a StudyKit server. The Image Background Remover is the exception, and it is worth being precise about why. Removing a background properly means telling a person, a product, or a piece of hair apart from everything behind it, which is a matter of recognising a subject rather than of comparing one colour with another. That needs a recognition model, and there is no version of one small enough to run usefully in a browser tab, so the picture is uploaded to the server that hosts this site and processed by a model that we run ourselves. The uploaded image is deleted as soon as the cut-out is finished. The finished PNG is kept for 30 minutes so that you can download it, adjust its edges, and download it again; after that it is removed, along with anything left behind by a request you abandoned. Your images are never used to train or improve the model, and no outside provider is given your picture or the result. Image to Text (OCR) is the same, with one detail worth stating plainly. Recognising text needs a recognition engine of roughly 16 MB, and the first time somebody asks for text that engine is downloaded from this site’s own address rather than from an outside provider, so no third party is told which visitors use the tool. The image being read stays on your device, and the words are shown only in the open page. Screen Recorder is also local: a recording is assembled in the page and offered to you as a download, and it is never stored here. If you turn on its optional microphone, any audio is captured and discarded in the same way. Video Auto Clip is local in the same way: a video you choose is read by your browser, measured frame by frame, and written back out as new MP4 files, and it is never sent to a StudyKit server. The clips are assembled in the page and offered to you as a download, then discarded when you clear them, reload, or close the tab. The engine that reads and writes the video is about 680 KB and is downloaded from this site’s own address on first use, so no outside provider learns that you used the tool. Re-encoding uses your browser’s own video encoder, and the sound from each clip is carried across with the picture rather than being sent anywhere. Because that encoder is only available over a secure connection, this tool needs the site to be served on HTTPS and says so plainly when it is not. Your browser may provide the requested image or permission result to the operating system, and normal hosting or browser services may process technical request data.

Text rewriting

The AI Text Humanizer rewrites text that you paste into it. Rewriting text with a language model means running that text through the model, and a model large enough to be worth using does not fit inside a browser tab, so your text is sent to a language model running on the server that hosts this site. It is not sent to any third party, and there is no external AI service in the chain. The text is held in memory only while it is being rewritten: it is not written to a file, and it is not kept once the response has been sent back to you.

The service records how each request went, not what you sent. Each log line holds the mode you chose, the word count before and after, whether the automatic quality checks passed or failed, and how long the request took. It does not hold your text, and the log is rotated and discarded on a schedule. Nothing you write is used to train a model.

Video Auto Clip

The Video Auto Clip tool works entirely on your own device. A video you choose is read by your browser and is never uploaded. The tool measures the video, scores its moments out of a hundred, and cuts the strongest ones into clips; choosing, previewing and exporting all happen in the tab, and the finished MP4 is written straight to your device. Because nothing is uploaded, there is nothing here for us to hold, and no retention period applies to your video or to the clips made from it. No account is needed, because there is nowhere for the file to go.

No part of your video, its audio, or the clips is sent to us or to any third party, and your video is not used to train or improve any model. The tool remembers only the small choices you make in it, such as the target clip length, whether to keep the sound, and the export shape, and it keeps them in your browser”s local storage on your own device rather than sending them to us. The chosen video, the analysis, and the finished clips are not stored. If your browser refuses local storage, or storage is full, the tool still works and simply stops remembering those choices. Clearing this site”s data in your browser returns it to the defaults; if you clear it before downloading, the clips are lost with it.

The result depends on your own machine rather than on a server. A browser that cannot encode the audio for the exported MP4 is told so in plain words, naming the browsers that can, instead of being handed a broken file. A long video on a phone is the case most likely to struggle, because the clip is held in memory while it is encoded.

Because nothing is uploaded, there is no question of who owns an upload: you keep the rights in your video and in the clips made from it. The Terms of Use cover copyright, what you are responsible for having permission to use, and how to report material you believe should be taken down.

Flashcards

The Flashcards tool is mostly a browser tool, with one step that cannot be. Decks, cards, and your review history are kept in your own browser using local storage. They are never uploaded, they do not follow you to another device or browser, and clearing this site’s data in your browser deletes them. Only your browser reads them, so nobody else, including us, can see a deck you have made.

Making cards from material is the exception. When you paste study material, or when you give only a topic, that text is sent to the server that hosts this site so a language model running on it can write the cards. It is not sent to any third party and it is not sent outside this machine. The material is read, turned into cards, and discarded: it is not written to a file, it is not kept, and it is not added to a log. Nothing you paste is used to train or improve a model. The cards that come back are saved in your browser, not on the server.

That tool records how each request went, not what you sent. Each log line holds the difficulty setting, how many cards were asked for, how many were produced, how many were rejected by the accuracy checks, whether the material was supplied, and how long the request took. It does not hold your material or your cards, and the log is rotated and discarded on a schedule.

Because the cards are written by a model running on our own server rather than looked up from a reference, a card can be wrong. Cards made from material you supplied are checked against it, and any card that uses wording or figures the material does not contain is discarded rather than shown to you, but this reduces mistakes rather than removing them. Cards made from a topic alone are not checked against anything, because there is nothing to check them against. Read the cards before you rely on them, and edit or remove any that are wrong: every card can be edited before it is saved and at any time afterwards.

Messages and contact information

If you email StudyKit or report a problem, the information you choose to provide is used to respond, investigate the issue, and maintain a record of the correspondence. Please do not send passwords, financial details, or unnecessary sensitive information.

Hosting and technical logs

WordPress, the hosting provider, and other infrastructure providers may record request data such as IP address, timestamp, requested URL, browser user agent, referrer information, and security signals. These records may be used for delivery, diagnostics, abuse prevention, and legal compliance. Their retention period is controlled by the relevant provider.

Advertising, cookies and local storage

StudyKit is funded by advertising. When you use this site, Google and its partners may place and read cookies in your browser, or use similar technologies such as web beacons, to collect information as a result of serving ads on this and other sites.

• Third party vendors, including Google, use cookies to serve ads based on a user’s prior visits to this website or other websites.
• Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.
• If you have not opted out of third-party ad serving, the cookies of other third-party vendors or ad networks may also be used to serve ads on this site. Those networks are identified on the ads themselves, and each publishes its own policy and opt-out page at aboutads.info.
• You may opt out of personalised advertising at any time through Google Ads Settings, or for a range of vendors at www.aboutads.info. You can also opt out of third-party vendor cookie use for personalised advertising on the vendor’s own site, where that vendor offers it.
• You can refuse or delete advertising cookies through your browser settings, and most browsers let you block third-party cookies for a site entirely. Doing so does not stop ads from appearing, but it does stop them being personalised using this and your other visits.

Google is the only advertising vendor currently used, and advertising is served on this site. Google Analytics 4, described in the previous section, is also in use to measure visits. Advertising and measurement are handled through Google Consent Mode: in the European Economic Area, the United Kingdom and Switzerland the advertising and storage signals start out denied, so nothing is stored or used to personalise advertising until you agree, and where a consent notice is required no advertising is served before that consent has been given. If another network, an analytics service, or any other component that places cookies is added later, this policy will be updated to name it and to link to its own policy before it is enabled.

WordPress, the theme, and plugins on this site may also set cookies or use browser storage for administration, preferences, security, search, and measurement. The Appearance control stores your choice in local storage on your own device: whether you have picked Match my device, Light, or Dark, which accent colour, and which reading size. That choice is not sent to us, is not tied to an account, and is not used to select advertising. Clearing this site’s data in your browser returns it to the defaults.

Analytics and site measurement

StudyKit uses Google Analytics 4 to measure how the site is used. It is installed by the Google Site Kit plugin, and when you load a page a script is requested from Google, which records your IP address, your browser user agent, the page you viewed, and the page that referred you. This is used to count visits, to see which tools people read about, and to find pages that are slow or need fixing. It is not used to try to identify you, and it does not receive the text, images, documents, or files you use in any tool, because those stay in your browser or are converted and then deleted as described above. Signed-in users, which in practice means the site editors, are excluded from measurement, so the figures are not distorted by our own visits. Google handles this information under its own privacy policy at policies.google.com/privacy, and you can stop measurement on other sites you visit with the Google Analytics Opt-out Browser Add-on.

Cloudflare Web Analytics is also enabled. It is a cookieless measurement tool: it counts page views and records the referring page and basic browser information, and it sets no cookies and builds no profile of you across other sites. It therefore does not appear in the Google Analytics Opt-out Browser Add-on, because it never identifies you in the first place. Cloudflare handles this information under its own privacy policy.

Measurement and advertising are both active now. A consent notice is shown to visitors in the European Economic Area, the United Kingdom and Switzerland. It covers measurement and advertising cookies together, so you can decline them without losing access to any tool, and it gives you the option to change your decision later.

Third-party services

The font used on this site is served from our own server rather than from a third-party font service, so simply loading a page does not disclose your IP address to a font provider. Page measurement contacts Google and Cloudflare as described in the sections above. Advertising is enabled, and Google is the only advertising vendor: its scripts receive your IP address, browser user agent and advertising cookies as described above. External links, if present, are governed by the linked site's own policy.

Security and retention

We use reasonable administrative and technical measures, but no internet service can guarantee absolute security. We do not retain tool text intentionally. The temporary files described above are held only for as long as they are needed to serve you: an uploaded document is deleted as soon as its conversion finishes, a background remover upload is deleted as soon as its cut-out finishes, a finished cut-out is kept for 30 minutes, a conversion result is kept for 45 minutes if you never collect it, and material pasted into the flashcard maker is discarded as soon as the cards have been written. Operational logs record what happened rather than what you sent, and are rotated on a schedule. Contact messages and provider logs may be retained for as long as reasonably needed for support, security, and legal obligations.

If you have found a security problem with this site, please report it to [email protected] rather than to the general support address, so that it reaches the right place. Please give us a reasonable opportunity to fix the problem before disclosing it publicly, and please do not test against other people’s data or access anything that is not yours.

Your choices

You can clear browser cookies and local storage using your browser settings. To stop your visits being measured by Google Analytics across every site you visit, you can install the Google Analytics Opt-out Browser Add-on linked above. You can also contact us to ask about information you have sent by email or to request a copy or deletion where applicable.

Contact

Questions about this policy can be sent to [email protected]. To report a security problem, please use [email protected] instead, which is read separately from general support.

Philippine data privacy law

StudyKit is operated from the Philippines and is subject to the Data Privacy Act of 2012 (Republic Act No. 10173), administered by the National Privacy Commission. This site is not offered to anyone outside the Philippines on different terms.

That Act gives you rights over personal data relating to you, which you can exercise by writing to the address in the Contact section above:

• To be informed about the personal data being processed about you, and the purpose of that processing.
• To object to processing, and to withdraw a consent you have given.
• To access and see the personal data concerning you.
• To have that data corrected.
• To obtain a copy of the data in a portable format.
• To have data erased or blocked, where its continued retention is not justified.
• To be informed of any automated decision-making that significantly affects you.

On this site the practical extent of those rights is small, and it is better to say so than imply otherwise. There are no accounts, so there is nothing tied to you. If you have emailed us or reported a problem, we hold what you chose to send, and we will tell you what that is, correct it, or delete it. If you have used a tool, the text, images or documents are handled as described in the sections above, and most of them never leave your device at all.

Where data is held by an infrastructure provider, the request comes to us first and we pass it on. We will tell you when that happens.

You also have the right to complain to the National Privacy Commission if you believe your data has been handled in a way that does not meet the Act. Raising it with us first is usually quicker, and most questions can be answered that way, but that is your choice and not a condition.

Governing law

This policy and your use of this site are governed by the laws of the Republic of the Philippines, and the courts of the Philippines have jurisdiction over any dispute arising from them.

Changes

We may update this policy as the site or its providers change. The date at the top identifies the latest version.
