SumacPrivacy Policy
Sumac ("the app") and sumacguide.com are operated by Dermatological Beauty LLC ("we", "us"). This policy explains what information we handle, why, and the choices you have.
Summary
- You can use Sumac without creating an account.
- Your location is used to search for restaurants and is not stored by us.
- We do not sell your data, show ads, or track you across other apps and websites. Anonymous usage statistics can be turned off in the app.
- You can delete your account and its data from inside the app at any time.
Information we handle
App identifier
When you first open Sumac, an anonymous account is created with a random identifier so the app can save your preferences and favourites. It contains no name or contact details.
Sign in with Apple or Google (optional)
If you choose to sign in, we receive your name, email address and, for Google, your profile photo. If you use Apple's "Hide My Email", we receive a private relay address instead. We use these to identify your account, show your name in your profile and next to your reviews (as your first name and the initial of your last name), and to contact you about your account or a support request.
Preferences and favourites
The diets and cuisines you select and the restaurants you save as favourites (stored as restaurant identifiers).
Reviews, ratings and diet confirmations
When you rate a restaurant, write a review, confirm a diet label or report a review, we store that contribution with your account identifier. Reviews, star ratings and your displayed name are visible to other Sumac users.
Location
With your permission, your device's location — or the map area you choose — is sent to our servers to search for nearby restaurants and, if you request directions, to calculate the route. We pass it to Google Maps Platform to perform the search and do not store it.
Usage limits
To apply the free plan's limits, we keep simple daily counters (such as the number of searches) and the identifiers of restaurants whose details you opened.
Purchases
Subscriptions are processed by Apple. We never receive your payment details. We receive and store transaction identifiers and expiry dates from Apple to activate Premium on your account.
Support messages
If you contact us by email or through our contact form, we receive your email address, your message and any details you include (such as your device and app version) and use them only to answer you.
Usage statistics
To understand how Sumac is used and improve it, the app records anonymous usage events with Google Analytics for Firebase — for example which screens are opened, which filters are chosen, which restaurants are viewed (by Google place identifier), where they appeared in the results, and whether directions, calls or websites were opened. These events are tied to a random app-instance identifier, not to your name, email or account identifier. We do not collect your device's advertising identifier, do not use this data for advertising and do not track you across other apps or websites. Your precise location is not included (only distance and the city or area you searched). In the EU/EEA, the UK and Switzerland we ask for your consent first; everywhere else you can turn statistics off at any time in Profile → Share usage statistics. We may combine these events into aggregated reports (for example, how many people viewed or got directions to a restaurant) and share only such aggregated, non-identifying figures with restaurants or partners.
On your device
Restaurant photos are cached temporarily on your device to load faster and are removed automatically.
Service providers
We rely on a small number of providers who process data on our behalf:
- Google Firebase (Google LLC) — accounts, database and server functions, hosted in the European Union (Belgium region). Firebase App Check uses Apple's App Attest to confirm requests come from the genuine app.
- Google Analytics for Firebase and Google BigQuery (Google LLC) — anonymous usage statistics described above, kept for up to 14 months in Analytics and stored for analysis in the European Union.
- Google Maps Platform — restaurant search, details, photos and directions. Google's Privacy Policy applies to its handling of these requests.
- Apple — Sign in with Apple and App Store purchases.
- Cloudflare — hosting of this website and delivery of support email.
Why we use your information
We use information to provide the app's features you ask for (performing our agreement with you), to keep the service secure and prevent abuse, and to answer your requests (our legitimate interests). Location is used only with your permission, which you can withdraw in your device settings at any time. Usage statistics are based on your consent where the law requires it, and otherwise on our legitimate interest in improving the app; you can turn them off in Profile at any time.
Emails
We do not send marketing emails unless you explicitly opt in. You can unsubscribe from any such email at any time.
How long we keep it
We keep your account data until you delete your account. Support messages are kept as long as needed to resolve your request and for a reasonable period afterwards.
Deleting your account
In Sumac open Profile → Delete account. This permanently deletes your account, preferences, favourites and written reviews. You can choose whether your star ratings and diet confirmations stay anonymously (with no link to you) to help other travellers, or are deleted too. You can also ask us to delete your account by emailing support@sumacguide.com. Deleting your account does not cancel an App Store subscription.
Your rights
Depending on where you live (for example under the GDPR or Turkey's KVKK), you may have the right to access, correct, delete or export your personal data, to object to or restrict certain processing, and to complain to a data protection authority. To exercise these rights, email support@sumacguide.com.
Children
Sumac is not directed at children under 13, and we do not knowingly collect personal data from them.
International transfers
Our providers may process data outside your country, including in the United States. Where required, they rely on appropriate safeguards such as the EU Standard Contractual Clauses.
Changes
If this policy changes, we will update this page and the date above. Significant changes will be announced in the app.
