The short version
- The public tools read your files in your browser and store nothing.
- Inside a project, what you upload, draw and write is stored privately under your account so you can come back to it. Only you can read it, unless you choose to share a book.
- We never use your artwork, scripts or results to train models, and never show your work as an example anywhere.
- Pro is paid through Stripe. We never see your card number.
Standalone tools
The tools under /tools run entirely in your browser. Files you drop into them are read on your device, never uploaded, never logged. Close the tab and they are gone. Saving a result to a project stores the numbers of that result (sizes, verdicts, a one-line summary), not the file.
Projects: what is stored
When you work inside a project, these things are stored so the app can work:
- Settings and structure: title, description, trim, bleed, resolution, page count, binding, cover choices, journey stage, page order, sharing settings, tags, and saved tool results.
- Your script, as the text you typed or imported.
- Uploaded pages: the original file at the size you uploaded, plus a web-sized copy and a thumbnail that your browser makes at upload time for previews.
- Drawings made in ComicCraft: the vector document of each page (the strokes, layers and balloons), its last ten earlier saves so you can go back, a web-sized copy and a small preview image.
- Reference pictures you pin beside a page while drawing.
Files live in a private storage bucket in your account's own folder. Nobody else can list or open that folder. The app hands you short-lived signed links to your own files when it needs to show them. Deleting a page removes its files; deleting a project removes everything in it, and there is no undo.
Sharing, and what readers can see
Every project starts private. If you set a book to unlisted, anyone with the link can open the reader. If you set it to public, it is also listed on the showcase and on your creator page. In both cases readers receive only the web-sized copies of your pages, never the print originals, and only for pages you have added to the book. If you switch on "Share the journey", readers and your followers also see which stage the book is in and how many pages are done. Turn a book back to private and all of that stops being visible.
Likes, comments and follows are stored with the account that made them and shown to the people involved. Comments you make on someone's book are visible to that book's readers; the owner can hide them.
Your account
We keep your email address and, if you use one, a password hash, so you can sign in. You can also sign in with a one-time link or code sent to your email. Your profile (display name, handle, bio, links, picture and cover) is public on your creator page once you set a handle.
Sign-in uses cookies that hold your session. Three small cookies do one job each: one remembers the last project you opened so the site can offer a way back to it, one remembers light or dark, and one gives a signed-out reader of a shared book a random id for a year, so a book counts each reader once. Your browser's own storage keeps a few drawing preferences and the ticks on the standalone checklist.
Signing in with Google
If you sign in with Google, Google sends us your email address, your name and your profile picture, and nothing else: we ask only for the basic sign-in scopes. The email identifies your account and is where we send account emails; the name seeds your display name, which you can change; the picture is not stored. We never read your Gmail, Drive, contacts or calendar, and we do not share Google account data with anyone. Deleting your account under Settings removes what we hold from Google along with everything else, and you can also revoke ComicCraft's access at any time from your Google account's security settings.
Sign-in links, confirmations, password resets, one welcome message, and a warning when your storage passes 80% and when it is full are sent from comiccraft.io through Resend, our email provider, which sees the recipient address and the message. Three getting-started tips in your first ten days, and occasional product news, go out only if you tick the box when you sign up or switch them on under Settings. Notices about comments and follows go out only if you switch them on. Each has an off switch under Settings. Payment receipts come from Stripe.
Feedback you send
A note from the feedback tab or the contact page stores what you typed, the kind you picked, the page you were on, your browser name, and your email if you gave one. If you were signed in, the note is tied to your account so we can reply. Your network address is kept only as a salted hash, to stop floods. Notes are read by Kutluozen Works LLCand nobody else: a copy arrives in our inbox by email, and the note is kept so we can follow up. Write to us to have yours deleted.
Measurement and error reports
Page views are counted with FocusStat analytics. It sees which pages are visited, not what you upload, draw or type.
ComicCraft also measures how the app itself is used, so we can make it better: which pages and tools are opened and for how long, which buttons are pressed, how long a drawing sitting or a reading lasts, which drawing tools and layers are picked up and whether a pen, a finger or a mouse holds the pointer, when the app turns a file away or a save fails and why, how fast pages load, and which link in one of our emails was clicked. We also record whether our emails were delivered. Each browser tab gets a random visit id that ends when the tab closes; nothing is kept in cookies for this. These records hold the account and the project involved, never file names, artwork or anything you wrote. They are kept for 180 days, only the people who run ComicCraft can read them, and deleting your account detaches them from you.
When something breaks, the app records the page, the tool and the error message so it can be fixed; those reports never include file contents or artwork.
Ads
The standalone tool pages and the blog posts each carry one ad from Google AdSense; it is what keeps the tools free. It is shown only to visitors who are signed out or on the free plan, and only on those pages: never inside a project, in the reader, on the showcase or on a creator page. If your account is on Pro, the ad code is not loaded at all.
Google and its partners use cookies to choose ads based on your visits to this and other websites. You can turn off personalised ads in Google's ad settings, and opt out of other ad companies' cookies at aboutads.info. Google explains how it uses information from sites that show its ads. In the EU, the UK and Switzerland you are asked before these cookies are set.
The ad code runs in your browser beside the tool. ComicCraft never passes it your files, and the tools still read them only on your device.
Where and with whom
Data is stored with Supabase (database and file storage) and served through Vercel; email goes through Resend. Payments for Pro go through Stripe, which receives your email address and card details; we keep only Stripe's references to your customer record and subscription, the subscription's status and its renewal date. All of them act on our instructions to run the service. We do not sell data, and we do not give your artwork to anyone. No third party is sent your artwork to process it.
Google, which serves the ads described above, is not one of them: it decides what its ad code collects under its own privacy policy.
What we never do
- Use your artwork, scripts or results to train models, ours or anyone else's.
- Show your work as an example or in marketing.
- Make a project visible to others without you choosing to share it.
Questions and removal
Delete a project from its settings, or delete your whole account under Settings: the account, its projects, drawings, comments and stored files go at once, with no grace period, and a Pro subscription is cancelled. Stripe keeps its own record of past payments. For anything about this page, contact Kutluozen Works LLC at hello@comiccraft.io.
