Privacy Policy
Last updated 8 October 2026
This page explains what data Quanthetic handles, where it's kept and what
control you have over it. It covers quanthetic.pages.dev and both apps on
it. The honest summary is that we collect almost nothing, because there is
nothing to sign up for.
The short version
There are no accounts. Your strategies, drawings, settings and backtest
history are stored in your own browser and never sent to us. Our servers
only see the requests your browser makes for prices, along with the
technical details every website receives, such as your IP address.
When a chart shows live prices, your browser also connects to
biquote.io, the service that supplies them. We don't use cookies,
analytics, ads or trackers, and we don't sell anything.
1. Who is responsible for your data
Quanthetic is made and run by AdarshXD (Adarsh Rao), one person based in
India. Under data
protection law that makes us the "controller", or the "data fiduciary"
under India's Digital Personal Data Protection Act, 2023. For any privacy
question, request or complaint, write to
xd.adarsh.xd@gmail.com. That
is also our grievance contact under the DPDP Act.
2. What reaches us
Price requests
The market, timeframe and date range your browser asks our server
for, so it can send back the candles. They aren't stored against you
or linked to anything else about you.
Technical data
Your IP address, browser type and similar details that come with
every web request. Cloudflare, our host, processes these to deliver
the site and protect it from abuse. We can see overall traffic
figures, not individual visitors.
Email
Only if you write to us. We use it to reply and keep it only as
long as we need to.
3. What stays on your device
These are saved by your browser, on your device, so the apps remember
your work. None of it is uploaded and we can't see it.
Strategy Lab
Your strategy code in each language, the market, timeframe and
history you picked, your layout, a cache of candles, and the log of
your past runs. In localStorage and IndexedDB.
Charts
Your drawings, indicators, chart style, layouts, saved replay
sessions and a cache of candles. In IndexedDB.
You can delete all of it by clearing this site's data in your browser
settings. Charts also has a reset under Settings, and the Lab can clear
its candle cache. Deleting it can't be undone, because we don't have a
copy.
4. How we use data
To send you the site and the prices you ask for, keep the service secure
and working, answer your email, and meet legal obligations. We don't sell
or rent personal data, use it for advertising, or build profiles.
5. Legal basis (GDPR)
If you're in the EEA or the UK: we process technical data and price
requests because we have a legitimate interest in running and securing
the service, and because it's needed to give you what you asked for. We
process email to reply to you, and anything else only where the law
requires it.
6. Cookies and local storage
We don't set cookies. The browser storage described in section 3 is
strictly necessary for the apps to remember your work, so no consent
banner is needed. There are no advertising cookies, analytics, tracking
pixels or session recording.
7. Who we share data with
Cloudflare hosts the site and our price service, under its own
privacy
policy. To answer a price request, our server fetches the files it
needs from our market data provider. Your IP address and browser details
are not passed on.
Live prices on a chart come from biquote.io, and your browser fetches
them from biquote directly rather than through us. That means biquote
receives your IP address and the technical details that come with any
request, under its own
terms and
privacy policy. Nothing else about you is sent to it, and it is only
contacted while a chart that has live prices is open. We may also share
data if the law requires it.
8. Data leaving your country
Cloudflare runs a global network, so technical data can be processed in
other countries, including the United States and the EU, under the
safeguards Cloudflare provides. biquote's servers may also be outside
your country.
9. How long we keep it
We don't keep price requests against you. Cloudflare keeps its own logs
under its policy. Emails are kept as long as needed to deal with them.
Data on your device stays until you delete it.
10. How we protect it
Everything is served over HTTPS. There are no passwords to leak, and your
strategy code never leaves your browser. The pages load no scripts from
anyone else.
11. Your rights
Wherever you live, you can ask us what personal data we hold about you
and how we use it, and ask us to correct or delete it. Under India's
DPDP Act you can also nominate someone to act for you, and take a
complaint to the Data Protection Board of India if we don't resolve it.
In the EEA and the UK you can also object, ask for restriction or
portability, and complain to your local supervisory authority. In
California you can ask to know, delete or correct, and you won't be
treated differently for doing so; we don't sell or share personal
information. Since we hold almost nothing, most requests will be about
email. Write to xd.adarsh.xd@gmail.com
and we'll reply within the time the law allows.
12. Children
Quanthetic is meant for people aged 13 and over, and under 18 only with a
parent or guardian's consent. We don't knowingly collect data from
children. If you think a child has sent us personal data, contact us and
we'll delete it.
13. Changes to this policy
If Quanthetic ever adds accounts or starts collecting anything new, this
policy will be updated before that change goes live, and the date at the
top will change with it.
14. Contact and grievances
For privacy questions, requests or complaints, email
xd.adarsh.xd@gmail.com.
