Who we are
ThinkStacks is a software studio based in Lahore, with team members in Karachi and London. In this policy “ThinkStacks”, “we” and “us” mean the ThinkStacks team that runs thinkstacks.io. For any privacy question, email [email protected].
This policy covers this website. BizOS, our business software product, has its own privacy policy. Work we do for clients is covered by the written agreement for that project.
What we collect
When you use the contact form
- Your name, email address and message (required).
- Optionally: phone number, company, the service you are interested in and your budget range.
- Your IP address and browser type (user agent), stored with the enquiry to block spam and abuse.
When you contact us directly
If you email us, call us or message us on WhatsApp, we receive whatever you send and your contact details on that service.
When you browse the site
Like any website, our servers and our security and delivery provider (Cloudflare) process technical data such as your IP address, browser and the pages requested, to deliver the site and protect it from attacks. We do not use analytics, advertising or tracking cookies on this site.
How we use it
- To reply to your enquiry, discuss your project and send you a proposal you asked for.
- To keep a record of our conversations with you.
- To keep the site and contact form secure (for example, limiting how many messages can be sent from one network).
We do not sell your personal data, and we do not add you to marketing lists without your permission.
Where UK or EU data protection law applies, we rely on our legitimate interests in answering enquiries and running a secure website, and on taking steps at your request before entering into a contract.
Who we share it with
- Hosting and email providers that store and deliver our website and email for us.
- Cloudflare, which delivers and protects the website.
- Google Fonts: pages load fonts from Google, which receives your IP address when fonts are fetched.
- WhatsApp, only if you choose to message us there.
- Our group companies (DatumLabs, Bitwords, Rush Corporation), only when your project needs their involvement and you have agreed.
- Authorities, if the law requires it.
These providers may process data outside your country, including in Pakistan, the UK, the EU and the US.
How long we keep it
We keep enquiries for as long as we need them to respond and follow up, and for longer if you become a client, as part of our project records. You can ask us to delete your enquiry at any time.
Your rights
You can ask us to give you a copy of your personal data, correct it, delete it, or stop using it. Email [email protected] and we will reply within one month. If you are unhappy with how we have handled your data, you can also complain to your data protection authority — in the UK, the Information Commissioner’s Office (ico.org.uk).
Cookies
The public pages of this site do not set cookies. Our own staff area sets a login cookie for team members only. Cloudflare may set a strictly necessary security cookie to tell people and bots apart.
Changes
If we change this policy we will update the date at the top of this page.
