Privacy Policy
Effective date: November 8, 2026
Common Ground (commonground.quengadesigns.dev) is operated by Quenga Designs. This policy explains, in plain terms, what information the site collects when you use it and what happens to it. You can use the Rental Map, Community Resources and Work Hub without creating an account.
The short version
- We do not ask visitors for their name, email address or phone number, and there is no visitor account.
- We count page visits with privacy-focused analytics that do not use cookies, and we strip search terms and filters from what is counted.
- Work Hub caseload information stays on your own computer. It is never sent to this website.
- We do not sell or rent personal information, and we do not show advertising.
Information collected when you browse
Like nearly every website, the servers that host Common Ground automatically receive basic technical information with each request: your IP address, browser type, the page requested and the time. Our hosting provider, Vercel, keeps this in short-term server logs used to run the site, keep it secure and fix problems.
We use Vercel Web Analytics to see which public pages are used. It does not use cookies. Before anything is sent, the site removes the part of the web address after a "?" or "#" (which can contain your map filters or search terms). Visits to the staff area and the Work Hub are not counted at all.
Cookies and storage in your browser
Common Ground does not use advertising or tracking cookies. It stores a few small items in your browser to make the site work:
- A language preference (cg_lang) if you change the language of the Community Resources directory. It lasts one year.
- Your light or dark display setting.
- The list of services you pick for a printable resource sheet, so your picks survive a page reload.
- A sign-in cookie (admin_session) for staff only. It is set when a staff member signs in and expires after 30 minutes of inactivity or 8 hours at most.
You can clear these at any time in your browser settings. The site still works without them; your preferences just won't be remembered.
Services your browser connects to
To show the site, your browser loads content directly from a small number of other services, which receive your IP address as part of the normal connection:
- Supabase, which stores the site's property and service listings and photos.
- OpenFreeMap and Esri (ArcGIS Online), which provide the map tiles and aerial imagery on the Rental Map.
- Vercel, which hosts the site and provides the analytics described above.
Links such as "Directions" or "Street View" open Google Maps or other outside websites in a new tab. Those sites have their own privacy policies, and we do not control them.
Work Hub
The Work Hub is a case-management tool. The caseload (clients, households, notes, tasks and attachments) is kept in a file you choose on your own computer, with encrypted attachments and backup snapshots saved in your browser. Work Hub pages are built so that caseload information is not sent over the internet to this website or anyone else, and they load no analytics or third-party scripts.
Because we never receive your caseload, we cannot see it, recover it or restore a lost passphrase. Keeping the file safe and backed up, and following any privacy rules that apply to your organization (such as HIPAA or HMIS requirements), is your responsibility.
The Work Hub shares its web address with the rest of Common Ground. That means your browser treats them as one site: clearing site data for the Work Hub also clears your Common Ground preferences and any staff sign-in, and the reverse.
The Work Hub may also store a few settings in your browser, such as display preferences and which panels are open, and may save its own pages for offline use.
Staff accounts
Staff who maintain the listings sign in with a named account and a PIN. For those accounts we keep the staff member's name, a scrambled (hashed) version of the PIN that cannot be turned back into the PIN, a record of sign-in attempts in which the IP address is stored only in scrambled form, and a log of changes made to listings and accounts. This is used to keep the site secure and to know who changed what.
Information about properties and landlords
The Rental Map shows information about rental properties, such as addresses, rents, availability and the contact details of property management companies. It comes from public sources like county parcel records, HUD data and published rental listings. It is about properties and businesses, not about tenants or visitors. If information about you appears on the site and you want it corrected or removed, contact us using the details below.
How we use and share information
We use the information above only to run, secure and improve Common Ground. We do not sell or rent it, and we do not use it for advertising. We share it only with the service providers named in this policy so they can run the site for us, or when the law requires it.
How long we keep it
Server logs and analytics are kept for the periods set by our hosting provider. Staff sign-in records and change logs are kept for as long as needed for security and record-keeping, currently 12 months.
Your choices and California privacy rights
You can block or clear cookies and browser storage, and the site will still work. Depending on where you live, including in California, you may have the right to ask what personal information we hold about you, to ask us to correct or delete it, and to not be treated differently for asking. To make a request, contact us at marcel.quenga@quengadesigns.dev. We do not sell or share personal information for cross-context behavioral advertising.
Children
Common Ground is not directed at children under 13, and we do not knowingly collect personal information from them.
Security
The site uses HTTPS encryption and strict browser security settings, and staff access is limited and logged. No website can be perfectly secure, so please do not send us sensitive personal information by email.
Changes to this policy
If we change this policy, we will post the new version on this page and update the effective date above.
