1. Who we are
This policy covers the Stock Guide Signal app (Android and desktop), this website and the server they use. They are run by Stock Guide Signal (“we”, “us”). We decide how the data described here is used, so we are responsible for it. The policy follows India's Digital Personal Data Protection Act, 2023 and the Information Technology Act, 2000 and its rules.
2. Data that stays on your device
These are stored only on your phone or computer, in the app's own storage. We do not receive them:
- your trades, trade notes, day journal and reviews, trading accounts, fund ledger, settings and statistics;
- Excel exports and backup files you save to your device;
- broker trade books you import (they are read on the device);
- broker access tokens you enter, for example for Upstox market data. The app uses them only to talk to that broker.
If you back up to Google Drive, the backup goes to your own Google Drive account, using your Google sign-in on the device. We don't get access to your Drive. Google's privacy policy applies to that copy.
3. What reaches our server
Your account
- Mobile number: you log in with your mobile number and a one-time code (OTP) sent by SMS.
- OTP records: the code is stored only as a one-way hash, with the requesting IP address, to stop misuse.
- Login sessions: a login token, stored as a hash, with the device name, IP address and the time it was last used. We also record when you joined and last logged in.
Membership, add-ons and purchases
- Your package and add-ons: their start and end dates, the amount paid and your purchase history.
- For purchases in the app, Google Play handles the payment. We receive the Play order ID, the purchase token, the product, whether it was a test purchase, and Google's purchase status. We use these to check the purchase with Google and to handle refunds. To link a purchase to your account, the app gives Google a one-way hash of your mobile number, not the number itself.
- We never receive your card, UPI or bank details.
- For a membership activated by us directly, we keep a short note, for example how it was paid.
Server backup (optional)
If you use Server backup, the app encrypts the backup on your device (AES-256-GCM) with a passphrase that never leaves your device. We store the encrypted file and its label: backup name, size, time, device name, number of trades and whether it was automatic. We cannot open your backups. If you lose the passphrase, nobody, including us, can restore that backup.
Profit reward (optional)
If you claim a profit reward, the app sends that month's return %, net profit or loss, capital and number of trades, so that we can work out your discount. Nothing is sent unless you claim.
Bug reports and feature requests (optional)
When you send feedback, we receive what you write (title, details, steps), the app version and platform, the IP address, and your account if you are logged in. We also receive a screenshot and device details (model and system version), but only if you add them.
Update check
The app asks our server whether an update is available. It sends only the platform and the app's build number.
Server logs
Like any website, the server records technical data such as IP addresses and errors, to keep the service running and secure.
4. How we use it
- to log you in and keep your account secure;
- to provide your membership, add-ons, purchases, refunds and profit rewards;
- to store and return your encrypted backups;
- to answer your reports and improve the app;
- to prevent abuse, for example by limiting OTP requests and reports;
- to meet legal duties such as tax and accounting records.
We process this data with your consent when you sign up or use an optional feature, or because it is needed to provide what you asked for. We do not use your data for advertising, we don't build profiles about you, and we don't sell it.
6. How long we keep it
- OTP records: deleted after 1 day.
- Login sessions: until you log out or they expire, then deleted.
- Server backups: until you delete them in the app, or until your account is deleted.
- Account, membership and add-ons: while you have an account.
- Purchase and payment records: for as long as Indian tax and accounting law requires, even after your account is deleted.
- Feedback: until the report has been dealt with and we no longer need it.
7. Security
- The app talks to our server only over HTTPS.
- OTPs and login tokens are stored as one-way hashes.
- Server backups are encrypted on your device, and we never have the key.
- Screenshots and backup files are stored outside the public website.
- Only our administrators can use the admin panel. Their logins are protected and their changes are logged.
No system is perfectly secure. If a breach affects your data, we will inform you and the Data Protection Board of India as the law requires.
8. Your rights and choices
You can ask us to:
- tell you what personal data we hold about you and how we use it;
- correct or update it;
- delete it, or delete your account;
- withdraw consent for an optional feature: stop using it and ask us to delete what it sent (you can delete server backups in the app yourself);
- name another person to use these rights for you if you die or can't act yourself.
Write to us at the contact details below, from or mentioning the mobile number you log in with. We reply within 30 days.
You can also log out of all devices at any time from the app.
9. Deleting your account
To delete your account, write to the contact details below from or mentioning the mobile number you log in with. We confirm the request is yours, then delete your account, login sessions, server backups, profit rewards and feedback within 30 days. We keep only the purchase records the law requires (see section 6).
The data on your device is not affected: uninstall the app or clear its data to remove it. Google Drive backups stay in your Drive until you delete them there.
10. Children
The app is meant for adults who trade, and is not for anyone under 18. We don't knowingly collect data from children. If you believe a child has given us data, contact us and we will delete it.
11. Changes to this policy
We will update this page when the app or the law changes, and change the “Last updated” date. For important changes, we will also tell you in the app.
12. Contact and grievances
Stock Guide Signal
We aim to resolve complaints within 30 days. If you are not satisfied with our reply, you can complain to the Data Protection Board of India.
