Privacy Policy
SlideHUD lets you turn presentation slides with an Even R1 ring and read your speaker notes on Even G2 glasses. To do that, the SlideHUD app on your computer and the SlideHUD plugin on your glasses talk to each other through our relay service. This policy explains what that involves. It applies to the international edition of SlideHUD at slidehud.hsmdata.cloud.
Who we are
SlideHUD is operated by 上海桦书闽数据科技有限公司 (HSMData) (“we”, “us”). For anything about your data, email support@hsmdata.cloud.
What we collect
| Data | Why | How long we keep it |
|---|---|---|
| Account: email address, display name, profile picture URL, and the account IDs of the sign-in methods you use or link (Google, WeChat or an email code) | To sign you in and keep your devices and settings together | Until you delete your account |
| Devices: the name and type of each computer and pair of glasses you link (for example “Office-PC”, “G2”), when it was linked and last online | So you can see and remove your devices, and so commands reach the right computer | Until you remove the device or delete your account. Glasses that are never linked to an account are deleted after 24 hours |
| HUD settings: theme, notes length, timer, gestures and similar preferences | To apply the same settings on all your devices | Until you delete your account |
| Sign-in records: hashed session tokens, hashed one-time codes and short-lived login requests | To keep your account secure | Sessions expire after 180 days; codes after 10 minutes; login requests within a day |
| Purchases: plan, start and end dates, and the order reference from our payment provider | To unlock Pro features | As long as required for accounting and tax law |
| Technical logs: IP address, time, and the address of each request to our servers | To keep the service running and to stop abuse, such as automated sign-up attempts | Up to 90 days |
Your presentations
While you present, the SlideHUD app reads the open presentation on your computer and sends your glasses what they display: the file name, the current slide number and title, the next slide’s title, the current slide’s speaker notes, the slideshow status and elapsed time. This information passes through our relay in memory, is delivered to your glasses, and is discarded. We never store your slides, notes or file names on our servers, and the presentation file itself never leaves your computer.
If you use keyboard mode, the app also checks which program is in front (its process name, not its window title) so that it can tell you where the keystrokes will land. Talk history used for rehearsal statistics is kept only on your computer.
How we use data
Only to provide SlideHUD: signing you in, linking your devices, relaying commands and display content, syncing settings, providing Pro features you have paid for or are trialling, answering your support requests, and protecting the service. We do not sell your data, we do not show ads, and we do not use tracking cookies or third-party analytics. The website sets no cookies; the sign-in page stores your session in your browser’s local storage.
If you are in the European Economic Area or the UK, we process your data to perform our contract with you (providing the service you signed up for) and on the basis of our legitimate interest in keeping the service secure.
Who processes data for us
- Cloudflare, Inc. (hosting, database, email delivery). Our servers and database are hosted by Cloudflare, with the account database in North America.
- Google LLC and Tencent (WeChat), if you sign in with them. WeChat sign-in runs through our WeChat login service hosted on Alibaba Cloud in mainland China. They tell us your account ID and, depending on the provider, your email address, name and profile picture; we never receive your password.
- Creem, our merchant of record, which processes payments and taxes. They collect your payment details; we only receive the order reference, the plan you bought and your email address.
The glasses plugin runs inside the Even Realities app, which handles the Bluetooth link to your glasses and ring under its own privacy policy. We do not share data with Even Realities.
Your data may be processed in the United States and in other countries where Cloudflare operates. Where data leaves the EEA or UK, it is protected by the safeguards in our providers’ data processing terms, such as the European Commission’s standard contractual clauses.
Security
All traffic is encrypted in transit (HTTPS and secure WebSockets). Device keys, session tokens and sign-in codes are random and stored only as SHA-256 hashes on our side. On Windows, your device key is encrypted with your Windows account (DPAPI) before it is saved.
Your choices and rights
- Delete your account in the SlideHUD app under Account → Delete account. This removes your account, devices, settings and sessions right away. You can also email us.
- Remove a device at any time; its key stops working immediately.
- Access, correct or export your data, or object to how we use it, by emailing support@hsmdata.cloud. We reply within 30 days.
Depending on where you live (for example under the GDPR or California law), you may have further rights, including to complain to your local data protection authority. We do not sell or share personal information as those terms are defined under California law.
Children
SlideHUD is not directed at children under 14, and we do not knowingly collect their data.
Changes
If we change this policy in a way that matters, we will update the date above and tell you in the app before the change takes effect.
