Privacy Policy

Last updated: 25 July 2026

Short version: the apps collect nothing, this website has no analytics and sets no cookies, and the only personal data that reaches me comes from an order or from an email you send me. There is no account to create and no server for your files to go to.

Who is responsible

This site and the apps on it are made by Timotei Petre, an independent developer based in Romania, acting as data controller. You can reach me at hi@ontagonal.app for anything in this policy.

The apps collect nothing

ScreenGo, MouseScroll and Shelf run entirely on your Mac:

• No network access. ScreenGo runs inside Apple's App Sandbox with no networking capability at all — it cannot send data anywhere, because it has no way to reach the internet.
• No analytics, no telemetry, no crash reporting. Nothing is counted, timed, or reported.
• No account, no login. License codes are verified offline, on your machine.
• Your content stays yours. Screenshots, files you drop on a shelf, and anything else you handle with these apps never leave your Mac.

Where an app needs a macOS permission — ScreenGo needs Screen Recording in order to capture the screen at all — it is used only for that purpose, and macOS asks you first.

This website

The site is a set of static pages. It sets no cookies, runs no analytics and includes no third-party trackers, fonts, or scripts. There is nothing here that follows you.

It is hosted on Cloudflare Pages. Like any web host, Cloudflare processes technical request data — including your IP address — in order to deliver pages and protect against abuse. I do not receive individual visitor data from this and cannot identify you from it.

When you buy something

Purchases are not processed by me. FastSpring acts as the merchant of record: they are the seller for the transaction, they collect your payment and billing details, and they handle tax and invoicing. I never see or store your card details.

From a completed order I receive limited information — typically your name, email address, country, and what you bought — which I use only to deliver your license code and to help you if you write to me. FastSpring's own handling of your data is governed by FastSpring's privacy policy.

When you email me

Mail sent to hi@, support@ or billing@ontagonal.app is forwarded by Cloudflare Email Routing into a Gmail mailbox (Google). Your message and address are used to reply to you and are kept as long as the correspondence is useful for support.

What I never do

• Sell, rent, or trade your personal data.
• Build profiles, run ads, or use your data for advertising.
• Send marketing email you did not ask for.

Your rights

Under the GDPR you can ask for access to the personal data I hold about you, ask for it to be corrected or deleted, or object to its processing. Write to hi@ontagonal.app and I will respond. For data held by FastSpring as merchant of record, contact them directly — or write to me and I will point you the right way.

For order-related data there are limits: FastSpring and I may need to keep invoice records for as long as tax law requires, even after a deletion request.

Children

These apps are developer and productivity utilities. They are not directed at children, and I do not knowingly collect data from anyone.

Changes

If this policy changes, the date at the top changes with it. Material changes will be summarised here rather than quietly folded in.
