Files and text used in tools
The tools run locally in your browser: image conversion and cropping, photo-to-PDF, word counting, PDF merging, reading text aloud, and the ladder game. Utilark does not receive, store, or review the files, text, and names you use in them.
Reading text aloud has one exception that does not involve Utilark. Speech uses the voices your browser offers, and some browsers generate their higher-quality voices on their own servers rather than on your device. Choosing such a voice means your browser sends the text to its vendor to be spoken. The tool labels every voice as on device or network, lists on-device voices first, and warns before you play a network voice. Utilark neither receives nor can see that text either way.
Cropping a photo, converting it, or placing it in a PDF redraws the image, which discards the metadata a camera stores in the file — including GPS coordinates. This happens on your device and is a side effect of the processing, not something Utilark collects.
Closing or refreshing the page clears the tool state unless your browser itself retains form state. Downloaded results are saved wherever your browser is configured to save them.
Technical access data
The hosting and security providers may process standard request information such as IP address, browser type, requested URL, time, and security signals. This information is used to deliver and protect the website and may be retained according to the provider configuration.
Utilark keeps privacy-preserving daily usage totals for up to 90 days. To remove repeat visits from DAU, the date, connection IP address, and browser user-agent are converted into a keyed one-way daily value. The original values, individual browsing history, and cross-day visitor identifier are not stored in the Utilark analytics database. Known bots are excluded where Cloudflare signals or common automated user-agents identify them, and DNT or Global Privacy Control requests are not counted.
A page counts a visit again, separately, once it has been visible for three seconds or you have tapped, typed, or scrolled. This exists to tell people apart from things that only fetched the page, and it is sent as one empty beacon carrying no body. It is keyed by the same daily one-way value as the page view, so no additional information about you is stored, and the exclusions below apply to it identically.
An authenticated administrator can exclude the current browser from future counts. This setting uses the HttpOnly utilark_notrack cookie across utilark.app for up to five years, contains only the value 1, and is removed when the setting is turned off. It is not an advertising or cross-site tracking cookie.
Choosing a language stores the utilark_lang cookie across utilark.app for up to one year so that the site and its short tool addresses open in the language you picked. It holds only the value en or ko and is not used for advertising or cross-site tracking.
Contact messages
When you use the contact form, Utilark stores the message, category, language, submission time, status, and any reply email you choose to provide. A reply email is optional. Do not include sensitive information or attach private documents.
Contact messages are used only to review and respond to the inquiry. They are available to the Utilark administrator at admin.utilark.app, are kept separately from Bubblelab data, and are automatically removed after 180 days unless deleted earlier.
For abuse prevention, the service temporarily uses a keyed one-way value derived from the connection IP address. The original IP address is not stored in the contact database, and expired rate-limit records are removed automatically.
Tool feedback and published quotes
After using a tool, you may choose a helpful or not-helpful rating and optionally send a reason and a note of up to 180 characters. Utilark receives only those feedback fields, the tool address, language, and submission time. The file or text used in the tool is never attached to the feedback.
A note is private by default. A positive note can be considered for publication only when you separately select the anonymous-publication checkbox. Even then it stays hidden until the Utilark administrator reviews and approves it. No name, email address, IP address, or browser identifier is shown with a published quote.
Feedback, including approved public quotes, is removed automatically after 180 days unless deleted earlier. Ratings may be shown only as aggregate helpfulness totals once enough responses exist. A keyed one-way value derived from the connection IP address is used temporarily to limit repeated submissions; the original address is not stored in the feedback database.
Do not put a name, contact information, confidential material, or another person’s information in the short note. To request early removal of a published quote, send the exact quote and tool name through the contact form.
Advertising and analytics
The daily usage totals described above are stored in Utilark infrastructure and are visible only to the Utilark administrator. No third-party analytics script is loaded.
Utilark shows advertising supplied by Google AdSense. Google is a third-party vendor and, together with its partners, uses cookies or similar technologies to serve, personalize, and measure advertising based on your visits to Utilark and other websites.
Where consent is required, including the European Economic Area, the United Kingdom, and Switzerland, a Google-certified consent message is shown before advertising cookies are used for personalization. You can reopen that notice to change or withdraw your choice at any time.
You can turn off personalized advertising in Google Ads Settings, and you can opt out of third-party vendor cookies through the industry choice pages linked below. Turning personalization off does not remove advertising; it makes the advertising less specific to you.

Who is responsible
Utilark is an independent project operated by the maintainer of the public utilark.app source repository. There is no parent company, and the service is not operated on behalf of Bubblelab.
For a privacy question, a correction or deletion request about a contact message, or an advertising question, use the contact form. Replies go to the email address you choose to provide.
