Privacy Policy

Where we stand on privacy

SkipDelta is a browser extension that helps you understand DeltaMath coursework. To do that, we hold a small amount of information about you and your use of the tool. This policy lays out what that is, why we keep it, and where the lines are. The headline you should remember: we don't sell your personal information, and we only share it in the limited ways spelled out below.

What we keep

Here's the information that passes through SkipDelta:

• Account basics — your name, email, and the username and password you set up. If you tell us your school or grade level during signup, that's here too.
• Login and access records — the user and account IDs, session tokens, and subscription status we need to sign you in and remember which plan you're on, plus a history of account access for security.
• How you use the tool — when you open it, which features you use, the math topics you work on, session length, and your settings.
• Payment details — what's needed to process a purchase, such as a PayPal email or card information handled through our payment processor.
• Device and connection info — your IP address and rough location, browser type and version, operating system, and diagnostic logs or error reports that help us keep things running.

Why we keep it

We only use your information to run SkipDelta and make it better. In practice that means:

• Signing you in and keeping your session secure.
• Delivering the extension's features and the DeltaMath solutions you came for.
• Processing payments and tracking your subscription.
• Spotting and blocking fraud, abuse, or unauthorized access.
• Understanding which features help, so we can improve the tool.
• Answering you when you reach out for support.

When information does leave us

We don't sell or trade your data. There are only a few narrow cases where it's shared:

• Service providers — trusted vendors who handle things like payments, hosting, and analytics on our behalf. They're bound to protect it and can't use it for anything else.
• Legal reasons — if the law or a legitimate law-enforcement request requires it, or if we need to act to protect people's safety or our own rights.
• A change in ownership — if SkipDelta is ever merged, acquired, or its assets sold, your data may move as part of that deal. We'll let users know if that happens.

Cookies and other browser storage

SkipDelta's site and dashboard use cookies and similar browser storage (like local storage) for three jobs:

• Essential. Our own cookies and storage keep you signed in, remember where you are in checkout and which settings you picked, and help keep your account secure. If you turn these off, signing in may stop working.
• Analytics. Mixpanel shows us how people move through the product and through signup and checkout. Seline gives us privacy-friendly counts of who visits the site. Together they tell us what's working and what isn't.
• Ad measurement. The Meta Pixel helps us see how our ads perform and lets us build ad audiences on Meta.

When you pay, checkout is run by our payment provider, and it may set cookies of its own during that step.

You're in charge of all this. Your browser's settings let you block cookies or clear stored site data, and Meta's ad preferences let you change how it uses your activity for ads. And to be clear, none of this involves selling your personal information. We don't.

How long we keep it and how we protect it

We hold your information only as long as we need it to run the service and meet legal obligations, or until you ask us to delete it. To keep it safe we use encryption for sensitive data, tight access controls, session management with automatic logout, routine security reviews, and regular backups. That said, no system on the internet is ever perfectly secure — so please do your part with a strong, private password and don't share your login.

Your choices

Depending on where you live, you can ask us to show you the data we hold, fix anything that's wrong, delete your data, hand you a copy, limit how we use it, or stop marketing emails. To make a request, submit it through our support ticket page (you don't need a SkipDelta account for that), or email [email protected] if you'd rather. We'll handle it within a reasonable time.

Students under 18

SkipDelta is built for high-school and college students, and it's meant to be used by students aged 13 and over. We don't knowingly collect information from children under 13, and we don't knowingly set up accounts for them. If we learn we've picked up data from a child under 13, we delete it promptly.

If you're under 18 — or under the age of majority where you live — you should use SkipDelta only with a parent's or guardian's permission, and any plan has to be bought by that parent or guardian, or with their okay. This lines up with what our Terms say about age and purchases.

If you're a parent or guardian and you believe a child under 13 has an account with us, or that a charge was made for a student without your consent, tell us through the support ticket page and we'll delete the account and refund any subscription attached to it.

Updates to this policy

We may revise this policy as SkipDelta changes or as the law requires. Updates take effect once posted, and the "Last Updated" date above shows when we last touched it. For big changes we'll give users a heads-up. Keep using SkipDelta after an update and you're accepting the new version.
